  • A new approach to Supporting Runtime Decision Making in mobile OLAP   Order a copy of this article
    by Djenni.Rezoug Nachida 
    Abstract: Mobile OLAP (On Line Analyses Processing) system offers to decision makers the real-time and relevant analyses anywhere and at anytime. In order, to generate them, a mobile OLAP should not only use user preferences, but also exploits information about contextual situation (meeting, business travel, office work, or home work) where analyses are done. For instance, when generating analyses, a mobile OLAP could take into account whether the decision maker's contextual situation is a business travel (uses a device with limited resources) or an office work (uses a device with high capacities). For this end, we investigate in this paper to propose a mobile context-aware recommender system (MCARS for short) based on both user preference and context. But, unfortunately, the limited resources in the MCARS make reducing a context acquisition a necessary need. To achieve this goal, our system proposes: (i) a learned approach which generates relevant contextual factors (contextual factors shown to be important); (ii) deduces a relationship between a context and user's preferences (called contextual preference s) and finally (iii) recommends a set of analysis based on user's contextual preferences

  • Fruit fly image segmentation and species determination algorithm   Order a copy of this article
    by Pei XU 
    Abstract: For large-scale, real-time and accurate monitoring of citrus orchard fruit flies, an algorithm was developed to identify three kinds of mature fruit flies as Bactrocera dorsalis, B. cucurbitae and B. tau (Dipetra: Tephritidae) based on machine vision technology. A fruit fly sample image library was produced and the body characteristics for distinguishing the three different kinds of flies were analyzed. Within the identification algorithm, image target and background region segmentation was conducted under the YCbCr color space and long-axis searching of the scutellum area. Image registration was achieved using Hough transform, and the BP neural network fruit fly identification model was established to distinguish the fruit fly in each image. Every algorithm in this study was programmed on Matlab software. The image registration algorithm was applied to 120 images, each of which contains a single specimen of Bactrocera dorsalis, B. cucurbitae or B. tau (Dipetra: Tephritidae) from the self-captured sample library. The BP neural network model was applied to the identification of the fruit flies. Experimental results indicated that: (1) the yellow scutellum at the waist and abdomen of three different kinds of fruit fly contained the largest yellow area within the body, thus it could be used as the long-axis searching area during image registration. The vertical yellow lines in the middle of the back torso of both B. cucurbitae and B. tau (Dipetra: Tephritidae) could be identified to distinguish these two types of fruit fly from the Bactrocera dorsalis. Further, the area rate of these lines to the whole body could be used to distinguish among the three types of fruit fly. (2) The image registration accuracy was 100% with an average registration time consumption of 0.4 seconds. (3) The BP neural network model accuracy was 100%, indicating satisfactory identification. Further research will focus on the improvement of the self-adaptive aspect of the threshold selection, since the threshold selection for target region segmentation was influenced by the experimental environment.

  • Boosting Prediction Performance on Imbalanced Dataset   Order a copy of this article
    by Masoumeh Zareapoor, Pourya Shamsolmoali 
    Abstract: Mining from imbalance data is an important problem in algorithmic and performance evaluation. When a dataset is imbalanced, the classification technique is not equally considering both the classes. It is obvious that the standard classifiers are not suitable to deal with imbalanced data, since they be likely to classify all the instances into the Majority class, which is less important class. Additionally some of the performance measurement, like accuracy- which is known to be bias metrics in the case of imbalance data-does not have a very good performance when the data is imbalance. In this paper we tried to apply various techniques that used commonly to handle class imbalance, before giving the data to the classifiers. But, the performance of the classifiers is found degrading because of the highly imbalanced nature of the datasets. Hence we propose an integrated sampling technique with an ensemble of AdaBoost to improve the prediction performance. Meanwhile, through empirical, we show the more appropriate performance measures for mining imbalanced datasets.

  • Convergence Analysis of Adaptive MSFs used for Acoustic Echo Cancellation   Order a copy of this article
    by Alaka Barik, Mihir N. Mohanty, Kunal Das 
    Abstract: Through the technology advancement grows day by day, new challenges raise accordingly. In modern era of communication echo cancellation is a major problem. Cancellation of acoustic echo from loudspeaker and microphone coupling is an essential as well as challenging task. Mostly the adaptive filters are used to cancel the echo in present scenario and many researchers are still working on this area. The LMS algorithm design is used extensively in communication networks to correct for the echoes created by line impedance mismatches and is useful to compensate for the imperfection in telephony networks. This paper shows how the LMS algorithm through Multiple Sub Filter (MSF) is useful to solve echo problems. A large amount of coefficients is required for acoustic echo cancellation for a long path. Similarly lengthy filter results slow convergence.This paper comprises this tradeoff using LMS algorithm for the echo cancellation purpose. The proposed algorithm is based upon decomposing a long adaptive filter into smaller sub filters. Different types of errors have been analyzed that is mean error , common error and combination of both. Also, the comparative analysis among Mean Error and common error analysis shows its performance in terms of convergence. Simulations results show that the decomposed algorithm shows better than the long adaptive filter.

  • Probability Least Squares Support Vector Machine with L1 Norm for Remote Sensing Image Retrieval   Order a copy of this article
    by Jinhua Zhu 
    Abstract: This paper proposes a probability least squares support vector machine (PLSSVM) classification method that aims at remote sensing image data, like high-dimension, nonlinearity, and massive unlabeled samples. Hybrid entropy was designed by combining quasi-entropy with entropy difference, which was used to select the most valuable samples to be labeled from a larger set of samples. An L1 norm distance measuring was then used to further select and remove outliers and redundant data. Finally, based on the originally labeled samples and the screened samples, the PLSSVM was gained through training. The experimental results of the classification of ROSIS hyperspectral remote sensing images show that the overall accuracy and Kappa coefficient of the proposed classification method are more accurate than existing methods. The proposed method obtains higher classification accuracy with fewer training samples, which makes it very applicable to current problems of classification.

  • Development and implementation of a wireless sensor system for landslide monitoring application in Vietnam   Order a copy of this article
    by Dinh-Chinh Nguyen, Duc-Tan Tran 
    Abstract: The effect of climate change and human activities leads to a series of dangerous phenomena, such as landslides, flood, etc. Therefore, it is necessary to build a system to monitor environmental hazards. There are some studies that built landslide monitoring systems based on wireless sensor network (WSN). However, there is not any WSN that is the best standard for landslide monitoring system. The energy saving which helps extend the lifetime of the landslide monitoring system is very important. This paper focuses on the development of a WSN system with the proposed energy efficient scheme. In this work, we build a complete system that consists of sensor nodes, a gateway node, a database, a website interface and an Android application for landslide monitoring application. The energy efficiency scheme is applied at sensor nodes to increase the lifetime of sensor node up to 154 times and significantly increase the rate of successfully received packets. The system is also assembled and measured in the lab and the outdoor to analyze initial results.

    Abstract: A 24 GHz automotive radar with Dual Frequency Modulated Continuous Waveform (FMCW) is proposed. By using this modulation waveform, the ghost targets can be avoided, especially in multi-target situations. Thus, the detection ability of radar systems can be significantly improved. In this paper, in order to generate the Dual FMCW signal, a Dual FMCW Modulation Control Logic (DFMCL) is proposed. This block incorporates a 24 GHz Fractional-N Phase Locked Loop (PLL), synthesize 24 GHz modulation waveform. The proposed architecture was designed using 130 nm CMOS process. Two alternative chirps of 12 ms and 6 ms were generated in the coherent processing interval. The modulation bandwidth was 200 MHz. Moreover, a radar transceiver, which consists of 24 GHz Dual FMCW generator and Monolithic Microwave Integrated Circuits (MMICs), was accomplished. A behavioural simulation was conducted to evaluate the operation of the proposed generator. Then, the transceiver was modelled for testing the detection ability of the automotive radar.

  • Optimised Cost Considering Huffman Code for Biological Data Compression   Order a copy of this article
    by Youcef GHERAIBIA, Sohag Kabir, Abdelouahab Moussaoui, Smaine Mazouzi 
    Abstract: Classical Huffman code has been widely used to compress biological datasets. Though a considerable reduction of size of data can be obtained by classical Huffman code, a more efficient encoding is possible by treating binary bits differently considering requirement of transmission time, energy consumption, and similar. A number of techniques have already modified the Huffman code algorithm to obtain optimal prefix-codes for unequal letter costs in order to reduce overall transmission cost (time). In this paper, we propose a new approach to improve compression performance of one such extension, the cost considering approach (CCA), by applying a genetic algorithm for optimal allocation of the codewords to the symbols. The idea of the proposed approach is to sacrifice some cost to minimise the total number of bits, hence, the genetic algorithm works by giving penalty on the cost. The performance of the approach is evaluated by using it to compress some standard biological datasets. The experiments show that the proposed approach improves the compression performance of the CCA considerably without increasing the cost significantly.

  • Sybil Attack Resistant Location Privacy in VANET   Order a copy of this article
    by Balaram Allam, Pushpa S 
    Abstract: Vehicular Ad Hoc Networks (VANETs) are more susceptible to a large number of attacks due to its open medium and anomalous nature. Location privacy is an imperative challenge in VANET, an attacker can easily trace the vehicle activities, if it has the knowledge of the location. In the most of the location privacy preserving mechanisms, each RSU provides secret information to a vehicle entered into the range, and it is known only to the corresponding RSU. However, these are vulnerable to Sybil attack, whereby a malicious vehicle compromises an RSU, and it pretends as multiple vehicles. Thus, an effective mechanism is in need to identify the attacker and compromised RSU in VANET. This paper proposes a Sybil Attack Resistant Location Privacy (SARLP) system to identify the attacker even a compromised RSU present in the VANET. The SARLP system employs a Location Privacy Unit (LPU) to provide an effective authentication mechanism. It hides the real identity of a vehicle by providing temporary key and a trusted certificate to the user, and thus improving the location privacy. The RSU imposes its signature on a generated secret random number of the vehicle entered into the region. Each vehicle and RSU maintain the random number secretly. If two vehicles communicate, sender reveals the sequence of secret random numbers received from different RSUs along its traveling path. The secret maintenance mechanism verifies the secret random number at the interference range of two RSUs, and thus a genuine RSU can successfully detect the compromised RSU. The simulation results show that the SARLP system achieves a higher level of location privacy preservation of vehicles and attack resilience in networks compared to the existing footprint scheme.

  • A trust management based on a cooperative scheme in VANET   Order a copy of this article
    by Ahmed Zouinkhi, Amel Ltifi, Chiraz Chouaib, Mohamed Naceur Abdelkrim 
    Abstract: VANET is a Vehicular ad hoc network, which is highly dynamic, self-organized and without a preexisting infrastructure. VANET works properly if the participating vehicles cooperate to ensure the exchange of packets. This special network confronts many constraints, such as attacks of malicious entity and absence of trust between nodes. To solve these problems, we proposed an approach having a decentralized architecture combining two models: the cluster model and the trust management model. Our approach encourages cooperation between vehicles by broadcast packets using the reward concept. It also ensures the detection of selfish nodes using the trust concept. By applying the punishment mechanism, our approach aimed to prevent malicious nodes from disrupting the network by injecting false information. Besides, in our network, we guaranteed authentic forwarding packets which were controlled by the group leader which takes the function of watchdog. Our approach is based on asymmetric cryptography, which used RSA encryption and digital signature to ensure security. The simulation results provided by the NS3 simulator showed that our approach has better performance.

  • Visible Light Communication based High-Speed High-Performance Multimedia Transmission   Order a copy of this article
    by Atul Sewaiwar, Samrat Vikramaditya Tiwari, Yeon-Ho Chung 
    Abstract: A novel scheme for high-speed high-performance multimedia transmission using visible light communication is presented. Initially, the multimedia image is converted to digital data. This digital data is divided into three sub-streams and each sub-stream is then transmitted via three parallel channels. Prior to transmission, each sub-stream data is modulated using On-Off Keying (OOK) modulation. Three parallel channels corresponding to each color (red, green and blue) of a RGB LED are utilized for transmission, thus giving a total of 9 channels. Color filters (CFs) and selection combining (SC) are also utilized for performance improvement and high speed transmission. Simulations are performed to evaluate the effectiveness of the proposed scheme. Results show that the proposed scheme is efficient in terms of bit-error-rate (BER) performance and data rate. Thus, it can effectively be used for high speed multimedia transmission.

  • Analysis of Energy Aware Job Offloading in Mobile Cloud   Order a copy of this article
    by Junyoung Heo, Hong Min, Jinman Jung 
    Abstract: Mobile cloud computing is the combination of cloud computing and mobile computing, and provides rich computational resources to a mobile computer. In mobile cloud computing, computation offloading techniques are used to overcome the limitations of resource-constrained mobile devices. Offloading techniques perform some parts of a job of mobile devices in the cloud in behalf of mobile devices. If the cost of the operation in that part of the job in a mobile device is larger than the cost associated with offloading, the part is executed in the cloud. Traditional cost analysis models for deciding which parts of a job to execute in the cloud or a mobile device were estimated by using only the cost of offloading, which is composed of data transfer and response time required for the function call. In this paper, we propose a novel offloading cost analysis model based on the data synchronization rate and the data exchange rate for the input of the function to improve the accuracy of offloading cost estimation. We confirm through experiments that the offloading technique with the proposed model can reduce the execution time of a job and consequentially improve the energy efficiency when compared to previous techniques.

  • Method of Trajectory Privacy Protection Based on Restraining Trajectory in LBS*   Order a copy of this article
    by Zwmao Zhao, Jiabo Wang, Chuanlin Sun, Youwei Yuan, Bin Li 
    Abstract: With the development of mobile positioning technology, location-based services are becoming more and more widely used in the life, but it has produced the security problem of the users privacy leakage. In this paper, the problem of user trajectory privacy protection in location-based services is introduced, and a method of trajectory privacy protection based on restraining trajectory in LBS is proposed. The proposed method is done by restraining the release of sensitive position and choosing a non-sensitive position that the user might stay at with the maximum probability to replace the sensitive position. So it will prevent the leakage of sensitive position of user's trajectory, and protect the user's activity trajectory, and give the method of calculating the privacy protection degree of restraining method.

  • An improved design of P4P based on distributed Tracker   Order a copy of this article
    by Lixin Li, Feng Wang, Wentao Yu, Xiuqing Mao, Mengmeng Yang, Zuohui Li 
    Abstract: The P4P architecture is mainly composed of appTracker, iTracker and Peer. The single appTracker manages sharing resources in the different ISP domains. Every Peer registers with appTracker when joining the network, and then requests resources from appTracker. In this architecture, there is too much workload for the single appTracker, thus, the bottleneck problem often appears when the scale of the network is enlarged in this centralized structure. An improved design of P4P based on distributed Tracker is proposed to solve the overload problem of single appTracker server. In the improved P4P system, a distributed Tracker overlay network replaces the appTracker to manage the resources in the different ISP domains. The functions of iTracker arranged by ISP are extended and the info interfaces of the iTracker are designed in detail in order to realize sharing the resources among the different iTrackers. The experiments prove that the P4P framework based on the distributed tracker can solve the server bottleneck problem and improve the scalability and stability while maintaining the characteristics of locality and transmission capacity.

    by Shengxiang Gao, Zhiwen Tang, Zhengtao Yu, Chao Liu, Lin Wu 
    Abstract: For the purpose of using Naxi syntax information efficiently, we put forward a method of Chinese-Naxi syntactic statistical machine translation based on the tree-to-tree model. Firstly, for using syntax information of source language and target language, collecting Chinese-Naxi aligned parallel corpus and making a syntax parsing on both side, the method obtains corresponding phrase structure trees of Chinese and Naxi. Then, by using GMKH algorithm to extract a large number of translation rules between Chinese treelets and Naxi treelets, inferring their probabilistic relationship from these rules, it obtains the translation templates. Finally, using these translation templates, through a tree-parsing algorithm, to guide the decoding, translating each Chinese phrase treelet in bottom-up, it obtains the final translation text. In comparison with the tree-to-string model, the experiments show that this method improves 1.2 BLEU value. This proves that both Chinese syntactic information and Naxi syntactic information are very helpful in improving the performance of Chinese-Naxi machine translation.

    Abstract: Nowadays, sensing, processing, and analysing of vibration signals are key components to structural health monitoring systems. Wireless-based data acquisition (DAQ) systems for vibration measurements become more and more important in the sensing and processing field. This paper presents a hardware and software design of wireless data acquisition system for this purpose.

    Abstract: The traditional Texture Analysis methods only use relative contribution of each face area to mark the global similarity. For solving the problem of feature extraction which cause by local instead of global, Weighted Estimation for Texture Analysis method (WETA) based on the Fisher Discriminative Analysis (FDA) is proposed. First, Local Binary Pattern (Local Binary Pattern, LBP) or partial Phase Quantization (Local Phase Quantization, LPQ) is used for image texture encoding. Then, the image is divided into Local small pieces which are all equal and not overlap. The most discrimination axis, which are extracted from similarity space, are applied into texture analysis by FDA method, then the best solution through weight optimization is given. Finally, in the, experiments on two major general face databases (FERET and FEI) verify the effectiveness of the proposed method. The experimental results show that compared with texture methods in other papers, the proposed method in this paper has obtained better recognition performance.

    Abstract: The mobility of nodes in a wireless sensor network is a factor affecting the quality of service offered by this network. We think that the mobility of the nodes presents an opportunity where the nodes move in an appropriate manner. Therefore, the routing algorithms can benefit from this opportunity. Studying a model of mobility and adapt it to ensure an optimal routing in an agitated network is the purpose of our work. We are interested in applying a variant of the mobility model RWP (named Routing-Random WayPoint "R-RWP") on the whole network in order to maximize the coverage radius of the Base Station (which will be fixed in our study) and thus to optimize the data delivery end-to-end delay.

Compared with the related algorithms, the presented algorithm can effectively balance the global and local search and improve optimization performances. Finally, MEPSO can better solve the problem of directing orbits of chaotic systems.

  • PRIVACY PRESERVING METHOD FOR KNOWLEDGE DISCOVERED BY DATA MINING   Order a copy of this article
    by Sara Tedmori 
    Abstract: In spite of its success in a wide variety of applications, data mining technology raises a variety of ethical concerns which include among others privacy, intellectual property rights, and data security. In this paper, the author focuses on the privacy problem of unauthorized use of information obtained from knowledge discovered by secondary usage of data in clustering analysis. To address this problem, the author proposes the use of a combination of isometric data transformation methods as an approach to guarantee that data mining does not breach privacy. The three transformation methods of reflection, rotation, and translation are used to distort confidential numerical attributes for the purposes of satisfying the privacy requirements, while maintaining the general features of the cluster in clustering analysis. Experimental results show that the proposed algorithm is effective and provide acceptable values for balancing privacy and accuracy.

  • Towards a robust palmprint representation for person identification   Order a copy of this article
    by Meraoumia Abdallah, Bendjenna Hakim, Chitroub Salim 
    Abstract: Biometrics, which refer to automatic identification of individuals based on their physiological and/or behavioral characteristics, is a widely studied field. This identification technology has rapidly evolving and it has a very strong potential to be widely adopted in many civilian applications such as e-banking, e-commerce, and access control. Among the physiological biometric modalities, those based on palm have received the most attention due to its steady and unique features, which are rich in information with a low resolution. Although there is several palm capture devices, however, no of them is apt to provide the full features of the same palm. By using different capture devices, the palm features can be represented with different formats such as: grayscale images, near-infrared images, color images, multispectral images and 3D shapes. In this context, we present in this paper a study that permits to propose robust palmprint representation for a reliable person identification system. Thus, a comparative study of the used palmprint image representations in the practice is performed. A new scheme for improving the person identification using the palmprint images is proposed. The proposed scheme uses the combination of several classifiers results. The discrete CoNtourlet Transform (2D-CNT) is used as feature extraction technique. At each level, the palm image is decomposed into several bands using the 2D-CNT technique. Subsequently, some of resulting bands are used to create the feature vector. Given this vector of features, two sub-systems can be created. The first one is based directly on this vector of features. While the second one uses the Hidden Markov Model (HMM) in order to modeling the feature vector. For the combination of classifiers results, the matching score level fusion strategy is used. The proposed system is tested and evaluated using several databases of Hong Kong polytechnic university that contain 400 users.

  • Robust Adaptive Array Processing based on Modified Multistage Wiener Filter Algorithm   Order a copy of this article
    by Peng Wang, Ke Gong, Shuai-bin Lian, Qiu-ju Sun, Wen-xia Huang 
    Abstract: Multistage Wiener filter (MSWF) is a very efficient algorithm for adaptive array processing because of low-complexity and prominent rank-reduction advantage. However, if training sample data was contaminated by outliers, especially when outliers having the same DOA with target emerge, the MSWF results will be decreased severely. In this paper, MSWFs backward iteration was improved, and median cascaded canceler (MCC) strategy was adopted so that optimal weighting calculation can be obtained via sorting and median processing, meaning impact of outliers were removed effectively. Blocking matrix solving of MSWF forward iteration was completed by Householder transform to enhance fix-point format performance. The new-designed algorithm attained excellent compromise between robustness and complexity. To verify presented algorithms performance, array with 50 elements was established in simulation platform, and the simulated results also proved it can cope with outlier-contaminated applications effectively.

  • Improving Multidimensional Point Query Search using Multiway Peer-to-Peer Tree Network   Order a copy of this article
    by Shivangi Surati, Devesh Jinwala, Sanjay Garg 
    Abstract: Nowadays, Peer-to-Peer (P2P) networks are widely accepted inrnmultidimensional applications like social networking, multiplayer games, P2Prne-learning, P2P mobile ad-hoc networks etc. Various P2P overlay networksrncombining Multidimensional Indexing(MI) methods are preferable for efficientrnmultidimensional point or range search in a distributed environment. However,rnpoint query search in existing P2P has limitations viz. (i) either doesnt givernsupport to MI or uses replications to support MI or (ii) point query search cost is limited to O(log2N). Hence, traditional MI techniques based on the multiway tree structure (having larger fanout) can be employed to enhance the multidimensional point query search capabilities. Based on our observations, a hybrid model combining m-ary (m fanout of the tree, > 2) P2P tree network and MI based on space containment relationships is preferred to reduce point query search performance bound to O(logmN) using single overlay network. The present paper shows how this model improves the search performance of the point queries in O(logmN) steps, independent of the dimensionality of objects.

    by Augustinus B. Primawan, Nitin K. Tripathi 
    Abstract: Wireless Local Area Network design needs more development to obtain appropriate and effective results. Site surveys in the design process give realistic results, but require time and effort. Developing ways of predicting signal strength using empirical models can give appropriate results in access point placement to get good signal coverage. Geospatial analysis, such as Inverse Distance Weighting, Kriging and Global Polynomial Interpolation, has been compared. This study showed that Kriging analysis is an appropriate method to predict value the coverage area. Furthermore, predictive signal strength models such as classical, empirical and COST 231 Hatta models have been studied. The empirical model was shown to do the best predictive calculations. The empirical model used to predict signal strength combined with Kriging geographical statistical analysis gave usable signal coverage prediction for access point placement. This model will support GIS spatial analysis tools to perform effective planning in access point placement.

    by Shulong Liu, Xudong Hong, Zhengtao Yu, Hongying Tang, Yulong Wang 
    Abstract: Feature-opinion pair identification includes opinion words, opinion targets extraction and their relations identification, is important for analysis online reviews. In this paper, we propose a feature-opinion pair identification method in two-stage based on dependency constraints according to the relationship between the identification of feature-opinion pair and dependency constraints. In the first stage, we construct dependency constraints based on the dependency information of words. Then, dependency constraints and seed words are employed to extract opinion words and opinion targets. In the second stage, we use opinion words and opinion targets extracted in the first stage to construct candidate feature-opinion pairs. Thereafter, integrate dependency constraints, location features and part-of-speech features into support vector machine to identify feature-opinion pair. Our experimental result using online reviews demonstrates that the proposed method is effective in the identification of feature-opinion pairs, and the F-score has reached 83.85%.

    Abstract: In this study, a construction methodology for Low-Density Parity-Check Convolutional Codes (LDPC-CCs) ensembles based on cyclically shifted identity matrices is proposed. The proposed method directly generates the syndrome former matrices according to the specified code parameters and constraints i.e. code-rate, degree-distribution, constraint length, period and memory, in contrast to the majority of the available approaches that produce relevant error-correcting codes based on either block ones, protographs or spatially-coupled type of codes. Simulation results show that the constructed ensembles demonstrate advanced error-correcting capability of up to 0.2 dB in terms of frame-error and bit-error rates at the convergence region, when compared with the performance of error-correcting schemes adopted by various communication standards, with equivalent hardware complexity even at short codeword-lengths. Specifically, the constructed LDPC-CCs have been assessed against the corresponding error-correcting codes used in WiMAX and G.hn standards for wireless and wireline telecommunications, respectively.

    by Anvar Narzullaev, MOHD Hasan Selamat, Khaironi Yatim Sharif, Zahriddin Muminov 
    Abstract: Nowadays, Wi-Fi fingerprinting based positioning systems provide enterprises the ability to track their various resources more efficiently and effectively. Main idea behind fingerprinting is to build signal strength database of target area prior to location estimation. This process is called calibration and the positioning accuracy highly depends on calibration intensity. Unfortunately, calibration procedure requires huge amount of time and effort, and makes large-scale deployments of Wi-Fi based indoor positioning systems non-trivial. In this research we present a novel location estimation algorithm for Wi-Fi based indoor positioning systems. Proposed algorithm combines signal sampling and hyperbolic location estimation techniques to estimate the location of mobile users. The algorithm achieves cost-efficiency by reducing the number of fingerprint measurements while providing reliable location accuracy. Moreover, it does not require any additional hardware upgrades to the existing network infrastructure. Experimental results show that the proposed algorithm with easy-to-build signal strength database performs more accurate than conventional signal strength based methods.

  • Target coverage algorithm with energy constraint for wireless sensor networks   Order a copy of this article
    by Liandong Lin, Chengjun Qiu 
    Abstract: As wireless sensor networks are made up of low-cost and low-power tiny sensor nodes, it is of great importance to study on how to both cover targets and save energy consumptions. In this paper, we propose a novel target coverage algorithm with energy constraint for wireless sensor networks. Wireless sensor networks can be described as a graph model, in which nodes and edges represent sensors and maximum signal transmission ranges respectively. Particularly, there types of sensor nodes are utilized: 1) base stations, 2) gateways, and 3) sensors. The main innovations of this paper lie in that we organize the network lifetime by a cycle mode, and divide the network lifetime to rounds of equal period. At the beginning of each round, sensors independently determine which sensing units should be turned on in the working step. Afterwards, the status of each sensing unit is determined by integrating the sensing ability and remaining energy together. Finally, we construct a simulation environment to test the performance of our algorithm. Experimental results demonstrate that the proposed algorithm performs better than the Remaining energy first and Max-lifetime target coverage scheme under various number of sensors and attributes, and performance of our proposed algorithm is next only to integer programming. Furthermore, we also find that the proposed algorithm is able to effectively cover target with low energy consumption.

  • Safety Message Data Transmission Model and Congestion Control Scheme in VANET   Order a copy of this article
    by Zhixiang Hou, Jiakun Gao 
    Abstract: When VANET meets large traffic density, Beacons produced by periodical safety message may occupy the whole bandwidth of channel, resulting in link congestion. In order to ensure the safety in message data transmission and promote the effectiveness of congestion control, in this paper, we propose an actively safe information congestion control framework via analyzing VANET features which contain channel detection, load estimation, congestion control, sending restoration, and so on. Therefore, we propose a novel congestion control mechanism based on adjusting Beacon frequency and Vehicle communication model. Based on the control theory and the features of VANET, an active safety information congestion structure is put forward at first. Then CACP algorithm is adopted to estimate the link bandwidth for congestion prediction. For periodic status messages and security messages a channel assignment algorithm is also proposed to ensure there is enough channel resource to transfer emergency messages. As a consequence of this, the status message accuracy and the system safety can be ensured and the number of accommodating users can be increased, which will avoid network congestion and improve the channel utilization. From the simulation results, it can be observed that the proposed algorithm can effectively and accurately detect link load degree, improve throughput, decrease delay, reduce networked energy consumption and then guarantee data fidelity. Finally, the conclusion can be drawn that the proposed can achieve a safe and efficient transmission mechanism for VANET

    by Changyu Li 
    Abstract: Intelligent traffic has demand for massive data environment and high performance processing, which needs cloud computing platform to process massive data, and applying distributed parallel guidance algorithms to improve system efficiency. Therefore, this paper proposes an improved scheme based on clouding computing ACS algorithm. It first adopts MapReduce to parallelize traditional ACS, to process the solving problem with distributed parallel mode, and to improve the defects in ACS. The improved ACS applies Map function to parallelize the part which has the most time consuming, that is, the independent solving process of each ant. Then Reduce function is used to describe the processes of pheromone updating and obtaining better solutions. Simultaneously, for the defects of ACS on long searching time, and premature convergence to a non optimal solution, we integrate simulated annealing algorithm to ACS and provide corresponding realization process. The experiments construct Hadoop cloud computing platform and the improved algorithm is operated and tested on this platform. By the analysis on experimental results, we find the parallel ACS designed by us has improved the query efficiency of the shortest path, which also has advantage on the performance of running time and speedup ratio compared to classic algorithms.

    Abstract: In this study, we investigate the user-perceived availability of M-for-N shared spare-server systems. We assume that there are N identical working servers, each serving a single user group, and M identical shared spare servers in the system. We also assume that the time to failure of the server is subject to an exponential distribution, and the time needed to repair a failed server is subject to the Erlang type-k distributions. Under these assumptions, our numerical computation shows that there exists an optimal size (M + N) for shared spare-server systems with respect to the availability and cost for a given condition.

  • Integration of a quantum scheme for key distribution and authentication within EAP-TLS protocol   Order a copy of this article
    by GHILEN AYMEN, Mostafa AZIZI 
    Abstract: The extensive deployment of wireless networks has led to a significant progress in security approaches that aim to protect confidentiality. The current methods for exchanging a secret key within Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) protocol is based on Public Key Infrastructure (PKI). Although this technique remains one of the most widely implemented solution to authenticate users and to ensure secure data transmission, its security is only computational. In other words, by the emergence of the quantum computer, the existing cryptosystems will become completely insecure. Improving the contemporary cryptographic schemes by integrating quantum cryptography becomes a much more attractive prospect since its technology does not rely on difficult mathematical problems such as factoring large integers or computing discrete logarithms. Thus, we propose a quantum extension of EAP-TLS that allows exchanging a cryptographic key and authenticating a remote client with unconditional security, ensured by the laws of quantum physics. PRISM tool is applied as a probabilistic model checker to verify specific security properties for the new scheme.

  • Data Dissemination on MANET by repeatedly transmission via CDN nodes   Order a copy of this article
    by Nattiya Khaitiyakun, Teerapat Sanguankotchakorn, Kanchana Kanchanasut 
    Abstract: Recently, many researches on MANET (Mobile Ad Hoc network) have been carried out due to its various applications in information exchange. The efficient data dissemination in such an infrastructure-less environment as MANET is considered as one of the challenging issues. This paper proposes to adopt the concept of CDN (Content Delivery Network) Technique, normally used in Internet, for disseminating information in MANET. The source node disseminates data to surrounding nodes by repeatedly transmitting batches of packets via a set of CDN nodes acting as relay nodes. Our proposed data dissemination technique via CDN nodes is developed based on the OLSR (Optimized Link State Routing Protocol) on MANET. The limited number of CDN nodes is selected from MPRs (Multi-Point Relay) in OLSR in order to optimally cover all subscriber nodes and to avoid the interference problem as well. The packets are transmitted from CDN to destination nodes using the broadcasting technique the same technique as the one adopted in MPR, a broadcasting technique. In this work, the performance of our proposed technique is evaluated in terms of probability of successful transmission by simulation using NS3. The performance is compared with the typical OLSR and the recent work called Clustering-based data transmission algorithm in VANET (Vehicular Ad Hoc Network). It is apparent that our proposed algorithm improves drastically the overall probability of successful transmission when comparing with the typical OLSR. Additionally, it achieves higher probability of successful transmission at high nodes density when comparing with Clustering-based data transmission algorithm in VANET. Finally, the closed-form mathematical expression of the probability of successful transmission of our proposed algorithm in multi-hop network environment is derived and verified.

    Abstract: Device-to-device(D2D) communications underlying cellular networks, results in the cellular interference to D2D User Equipment(DUE) which is larger than the D2D interference to Cellular User Equipment(CUE). A joint resource allocation scheme is presented to both perform user equipment pairing and power allocation to minimize total interference of DUE and CUE. The scheme is composed of two parts: in the first one the base station assigns power to each CUE and each D2D transmitter by graphic method, and in the second one it selects the optimal CUE to pair with D2D pair by modified Hungarian algorithm in order to minimize total interference. The simulation results show that the proposed scheme can not only decrease the interference caused by D2D pair and that caused by CUE, but also increase the number of permitted D2D connections.

  • A Cognitive Approach of Collaborative Requirements Validation based on Action Theory   Order a copy of this article
    by Sourour MAALEM, Nacereddine ZAROUR 
    Abstract: The requirements must be validated at an early stage of the analysis. Requirements validation usually involves natural language processing, which is often inaccurate and error-prone, or translated in formal models, which are difficult to understand and use for non-technical stakeholders. The majority of existing approaches for validating requirements are used in a heterogeneous process, using a variety of techniques, relatively independent without any methodological or cognitive approach through in which, mechanisms of human thought or artificial are used. In this work we present a cognitive approach to collaborative requirements validation based on the theory of action, through a set of steps that must increase the involvement of the Client in this stage of the engineering cycle; and to bring the customer mental model to the analyst one. In the proposed process, the analyst starts by extracting needs one by one from requirements documents. Each need goes through a step of formulating the intention, which results in a transformation of needs into requirements. This transformation is performed by respecting a new syntax in any generated a checklist (quality attributes) from the viewpoint of each stakeholder, followed by a step of specification of actions that engenders on the basis of the intentions, actions which the analyst perceives and verifies to build a rapid prototype of software interface, executable on machine. The customer perceives the prototype, interprets it and validates these needs. A valid needs database is created, needs that remain invalid must be negotiated, and if conflicts persist, another error base is created. At the end of this collaborative process of requirements validation, decisions will be made concerning who must participate during needs validation meetings with respect to the Mental Effort metric which will classify according to the mental difficulty of execution of the prototype, the articulatory and semantic problems, and measure commitment and motivation of stakeholders.

  • A Personalized Recommendation Algorithm Based on Probabilistic Neural Networks   Order a copy of this article
    by Long Pan, Jiwei Qin, Liejun Wang 
    Abstract: Collaborative filtering is widely used in recommendation system. Our work is motivated by the observation that users caught in their attention relationship network, and their opinions about items will be directly or indirectly affected by others through such a network. Based on behaviors of users with similar interest, the technique focuses on the use of their opinions to recommend items. Therefore, the quality of similarity measure between users or items has a great impact on the accuracy of recommendation. This paper proposes a new recommendation algorithm with graph-based model. The similarity between two users (or two items) is computed from the connections on graph with nodes of users and items. The computed similarity measure is based on probabilistic neural networks to generate predictions. The model is evaluated on a recommendation task which suggests that which videos users should watch based on what they watched in the past. Our experimental results on the YouKu and Epinions datasets demonstrate the effectiveness of the presented approach in comparison with both collaborative filtering with traditional similarity measures and simplex graph-based methods and further improve user satisfaction, our approach can better improve the overall recommendation performance in precision, recall and coverage.

  • Temporal Impact Analysis and Adaptation for Service-Based Systems   Order a copy of this article
    by Sridevi Saralaya, Rio D'Souza, Vishwas Saralaya 
    Abstract: Temporality is an influential aspect of Service-Based Systems (SBS). Inability of a service to achieve time requirements may lead to violation of Service-Level Agreements (SLAs) in a SBS. Such non-conformity by a service may introduce temporal inconsistency between dependent services and the composition. The temporal impact of the anomaly on related services and also the composition will need to be identified if SLA violations have to be rectified. Existing studies concentrate on impact analysis due to web service evolution or changes to a web service. There is a huge lacunae regarding studies on impact of time delay on temporal constraints of dependent services and obligations of business process. Although reconfiguration of SBS to overcome failures is extensively addressed, reconfiguration triggered due to temporal delay is not well explored. In this study we try to fill the gap between reconfiguration and impact analysis invoked due to temporal violations. Once the impacted region and the amount of temporal deviation to the business process are known, we try recovery by localizing the reconfiguration of services to the impacted zone.

    by Abdelhak EL MOUAFFAK, Abdelbaki EL BELRHITI EL ALAOUI 
    Abstract: Recently, the wireless networks, particularly the wireless Sensor Networks (WSN) occupy an important place in several application areas due to the progress in microelectronics and wireless communications domains. Thus, a set of researches had addressed this issue in order to broaden the possibilities offered by these networks and circumvent the encountered problems. The test of any new solution is an essential phase to validate its performances. This phase is done in network simulators; which NS is the most used. The impact of the physical layer and the radio signal propagation environment criteria on the simulations results is indisputable. In this context, and after presenting and classifying the radio propagation models, we study in detail the implemented models in NS-2. The focus is on the ability of these models to consider the characteristics of the wireless networks deployment environment (e.g. nature, position and mobility of the obstacles). And to consider the specificities of WSN, the effect of other parameters (e.g. antenna height) will be discussed.

  • An Agricultural Data Storage Mechanism Based on HBase   Order a copy of this article
    by Changyun Li, Qingqing Zhang, Pinjie He, Zhibing Wang, Li Chen 
    Abstract: With the development of agricultural space-time localization, sensor network and cloud computing, the amount of agricultural data is increasing rapidly and the data structure becomes more complicated and changeable. Currently, the widely used agricultural database is the relational database. This database handles a large amount of data with very limited throughput and is not suitable for organization and management of distributed data. Hbase is a non-relational database of distributed file storage built on Hadoop platform. Hbase is suitable for unstructured data storage database and it can handle large volume of data with high scalability. To better store agricultural big data in Hbase, we propose a special agricultural data buffer structure which stores data based on the data category and a two-level indexing memory organization strategy on HBase. The method proposed saves more than a quarter of the time compared to traditional buffering methods. Experimental results show the higher efficiency of the agricultural data buffer structure and memory-organization strategy.

  • A Real-time Multi-Agent System for Cryptographic Key Generation using Imaging-based Textural Features   Order a copy of this article
    by Jafar Abukhait, Ma'en Saleh 
    Abstract: Traditional network security protocols depend on exchanging the security keys between the network nodes, and thus opposing the network to different classes of security threats. In this paper, a multi-agent system for cryptographic key generation is proposed for real-time networks. The proposed key generation technique generates a 256-bit security key for the Advanced Encryption Standard (AES) algorithm using the textural features of digital images. By implementing this key generation technique at both the sender and receiver network nodes, the process of exchanging the security keys through the network would be eliminated, and thus making communication between network nodes robust against different security threats. Simulation results over a real-time network show the efficiency of the proposed system in reducing the overhead of the security associations performed by the IPsec protocol. On the other hand, the proposed agent-based system shows a high efficiency in guaranteeing the quality-of-service (QoS) of the real-time requests in terms of miss-ratio and total average delay through applying the best scheduling algorithm.

  • Coordinated Route Reconfiguration for Throughput Optimization under Rician Fading Channel   Order a copy of this article
    by Adnan Fida, Nor Tuah Jaidi, Trung Dung Ngo 
    Abstract: This paper focuses on the high throughput data transmission to deliver ample sensor data such as images or videos in a post disaster scenario using mobile wireless sensor networks. We formulate the route optimization problem in the presence of Rician fading channel. The coordinated route reconfiguration strategy integrates the communication quality, shortest path algorithm, particle swarm optimization, and mobility of multiple routers to optimize the end to-end throughput of data transmission routes. We show how a coordinator can be used for identification of routers with critical links and to gradually manoeuvre them towards a reconfigured route with higher end-to-end throughput. The evaluation of our solution shows that proposed strategy considers the inherent characteristics of Rician fading channel, and takes benefit of the routers mobility to provide routes with better performance as compared to the routes generated by non-coordinated route reconfiguration framework.

    Abstract: Wireless Video Sensor Networks (WVSNs) have recently emerged as a new class of sensor networks in which large amounts of visual data are sensed and processed in real-time. This kind of networks, strengthened with rotation capability for each video sensor node due to dramatic advances in miniature robotic and its accessible prices today in market, is envisioned to be deployed in the physical environment to monitor with a great flexibility a plethora of real-world phenomena such as surveillance, monitoring and disaster recovery. In this work, we aim to propose a model of WVSN for post-disaster management in order to assist search and rescue operations by locating survivors, identifying risky areas and making the rescue crew more aware of the overall situation. To build an overview of the environment and to assess the current situation, rotatable video sensors are randomly deployed and used to switch to the best direction with the purpose of getting high coverage while avoiding obstacles. To address fault tolerance problem in WVSN which may arise in case of possible damages caused by disasters, we build potential cover sets using redundant video sensors to unsure Field of Views coverage of failed nodes. We have conducted a set of comprehensive experiments using the well-know OMNeT++ simulator and the obtained results reveal that our proposal gives better performance in terms of coverage enhancement and fault tolerance.

  • Constructing collective competence: A new CSCW-based Approach   Order a copy of this article
    by Djalal Hedjazi 
    Abstract: Within the majority of contexts, it is persons that are considered to be competent or incompetent. However, in many cases it is the performance of groups and teams that is most important. This implies a concept of collective competence that integrates the set of skills in a group. In addition, the collective competence construction process is also enriched through collaboration which implies exchanges, confrontations, negotiations and interpersonal interactions. This paper presents our CSCW-based approach supporting collective competence construction. As a case of study, the industrial maintenance workspace is fundamentally a collaborative context. Our contribution in this area led us first, to analyze the related task in order to highlight collaborative maintenance vital needs and design the appropriate required group awareness supports which will be used to support collective competence. Finally, the experimentation study identifies the highly effective group awareness tools.

    by Bahia Zebbane, Manel Chenait, Chafika Benzaid, Nadjib Badache 
    Abstract: Topology control based sleep-scheduling aims at exploiting node redundancy to save energy and extend the network lifetime, by putting as many nodes as possible in sleep mode, while maintaining a connected network. In this paper, we propose a Redundancy aware Topology Control Protocol (RTCP) for a wireless sensor network which exploits the sensor redundancy in the same region. This is achieved by dividing the network into groups so that a connected backbone can be maintained by keeping a necessary set of working nodes and turning off the redundant ones. RTCP allows applications to parameterize the desired connectivity degree. It identifies node redundancy, in terms of communication; it groups redundant nodes together according to their redundancy degrees and threshold of connectivity level. Finally, it schedules nodes in groups for active or sleep mode. The simulation results illustrate that RTCP outperforms some other existing algorithms, in terms of energy conservation, network lifetime and connectivity guarantee.

  • Architecture for Gathering and Integrating Collaborative Information for Decision Support in Emergency Situations   Order a copy of this article
    by Tiago Marino, Maria Luiza Campos, Marcos Borges 
    Abstract: The involvement of citizens in supporting crisis situations is no longer a new phenomenon. In the past, the lack of data was one of the main barriers faced by public managers in the decision-making process. Today the situation has been reversed, such that the challenge faced is managing an excessive mass of data, which is totally dynamic and originating from different sources such as remote environmental sensors, social networks, response teams in the field. During an emergency response, the concern is no longer being able to collect data for a better understanding of the af-fected environment, but in knowing how to organize, aggregate and separate what is actually useful for crisis managers. This research proposes a collaborative information architecture that considers aspects from environmental complexity in the context of emergency scenarios, in order to support response teams with decision making, through gathering and integrating information that has originated from different media resources and, hence, enriching a decision teams Current Contextual Knowledge base.

  • A Framework combining Agile, User-centered design and Service Oriented Architecture approaches for Collaborative Disaster Management system Design   Order a copy of this article
    by Karima Ait Abdelouhab, Djilali Idoughi, Christophe Kolski 
    Abstract: Disaster Management is a special type of human complex organization in which heterogeneous human actors belonging to different authorities collaborate and work together with the shared aim to solve, or at least reduce, the disaster situation. Thus, the collaboration in this case within team members and with other teams operating at the disaster site(s) is very critical and complex; the achievement of the desired goal heavily depends on this collaboration. Interactive and easy to use services in these scenarios are very valuable and necessary as they can improve collaboration, coordination, and communication amongst team(s) to achieve the desired goals. For this purpose, in this paper, we propose a novel design framework for complex disaster management systems. We combine agile characteristics and principles, user-centered techniques and service oriented architecture paradigm. Our aim is to take into account the needs of the disaster managers in an iterative development process, to improve the human actors involvement in the design projects, to offer the possibility to accept any changes in order to produce highly usable and interactive service based collaborative services.

  • A Hybrid Ad Hoc Networking Protocol for Disaster Recovery Resource Management   Order a copy of this article
    by Doug Lundquist, Aris Ouksel 
    Abstract: Following a major disaster, the infrastructure supporting wired and mobile networking is expected to be inoperable over large areas. Thus, emergency response teams must communicate using their own networking equipment. A large-scale peer-to-peer network offers fast and flexible deployment but requires cooperation among nodes. Usage constraints must be imposed to prevent overloading the shared network capacity. In particular, disparate communication models (for route building and optimization, resource management, and localized status flooding) must be integrated. We propose a hybrid network protocol which dynamically assigns network capacity to these three communication models by imposing transmission delays in accordance with their attempted usage rates.

    by Mohamed Hefeida, Ashfaq Khokhar 
    Abstract: Wireless Sensor Networks (WSNs) are being integrated across a wide spectrum of military, commercial, and environmental applications, such as field surveillance, environmental monitoring, and disaster management. This variety in WSN applications led to the development of a large number of Medium Access Control (MAC) protocols with different objectives. A common goal of these protocols however, is preserving energy in order to maximize network lifetime. In an effort to facilitate studying existing MAC protocols and developing novel medium access techniques, this paper presents a classification and critical review of existing MAC protocols adopted in different WSN environments. We classify these protocols based on channel access into three main categories: contention-based, contention-free, and hybrid protocols. Cross-Layer protocols (involving MAC layer) are also studied. We describe major characteristics of these classes, differences among them, possible improvements, and outline ongoing and future research challenges.

    Abstract: Quantum cryptography discusses the security of quantum information. Cloud computing has emerged as a computational paradigm and an alternative to the conventional computing. Cloud security is associated with cloud computing. In this paper, we define the new concept about quantum cloud and discuss the security of quantum information exchange in quantum internet. A tripartite simultaneous quantum information exchange protocol associated with the quantum cloud based on entanglement swapping and Bell states is proposed. The proposed secure quantum information exchange protocol can resist intercept-and-resend attack, intercept-and-measure attack, intercept-and-entangle auxiliary attack and denial-of-service attack. It can also be generalised to N-party case that is feasible and efficient.

    Abstract: Anonymous authentication is very useful to protect the user's privacy, and plays an important role in building e-commence where involves many partners, such as in cloud computing. With the anonymous property, ring signature provides a cryptographic tool to construct a secure authentication scheme. In this paper, we construct an identity-based ring signature (IBRS) based on Garg-Gentry-Halevi (GGH) graded encoding system which is a candidate multilinear maps from ideal lattice, and prove its security in random oracle model. Under the GGH graded decisional Diffie-Hellman (GDDH) assumption, the proposed ring signature guarantees the anonymity of signer against full keys exposure attacks. Considering unforgeability, under the GGH graded computational Diffie- Hellman (GCDH) assumption, the new scheme provides unforgeability both against selectively chosen subring attacks and insider corruption.

  • An efficient speech perceptual hashing authentication algorithm based on DWT and symmetric ternary string   Order a copy of this article
    by Zhang Qiuyu, Xing Pengfei, Huang Yibo, Dong Ruihong, Yang Zhongping 
    Abstract: According to the situation that speech perceptual hashing methods are not appropriated for real-time speech content authentication in mobile computing environment, a novel DWT-based perceptual hashing algorithm, which uses a combination of time-domain and frequency-domain features, was proposed to protect the speech data in the cloud. Firstly, by discrete wavelet transform (DWT), a new signal in frequency-domain is generated from the original speech signal after pre-processing and intensity-loudness transform (ILT). Secondly, coefficients of low frequency wavelet decomposition are partitioned into equal-sized and non-overlapping blocks, and logarithmic short-time energy of each block is computed to obtain speech signals features in frequency-domain. Finally, combined with spectral flux features (SFF) of speech signal in time-domain, a ternary perceptual hashing sequence is created. Experiment results illustrate that ternary form is better to stand for hash digest than binary form, the proposed algorithm has a good robustness against content preserving operations, discrimination, good compaction and high efficiency, and detects the tamper localisation as well.

  • Intelligent phishing detection system using similarity matching algorithms   Order a copy of this article
    by Ankur Mishra, B.B. Gupta 
    Abstract: Today, phishing attack is one of the most common and serious threat over internet. It is used to fraud users and steal their personal information either by using spoofed e-mails or fake websites or both. In this paper, we proposed a novel intelligent phishing detection system, i.e., CSS and URI matching-based phishing detection system (CUMP) to detect zero-day phishing attacks. Our proposed approach is based on the concept of uniform resource identifier (URI) and cascading style sheet (CSS) matching. This concept is used, as phisher always tries to mimic the URI pattern and visual design in the hope that even experienced user will not be able to detect phishing website by visualisation. To mimic the visual appearance, phishers generally use same CSS style. Without using same CSS, it is very difficult to achieve the same design. To defend against phishing websites attacks especially 'zero-day' attacks, our proposed system used the basic properties of any phishing attacks for URI and CSS matching. Our proposed solution is very effective in detecting a wide range of website phishing attacks with TP and TN rate of 93.27% and 100%, respectively and results in less false positive rate.

    by Syam Kumar Pasupuleti 
    Abstract: In multi-cloud storage, the data owners host their data and access the data from cloud servers. However, this new paradigm of data hosting service also introduces new security challenges such as integrity, availability and confidentiality of data. The prior works on ensuring remote data integrity in multi-cloud storage often lacks the address of confidentiality and availability issues, which are always important aspects of quality of service (QoS). In this paper, we propose an effective and secure data storage protocol in multiple cloud. In our design, we encrypt and encode the data before outsourcing into clouds to ensure confidentiality and availability of data respectively. Then, we consider the third party auditor (TPA) to verify the integrity of the data stored in the multi-cloud and extend verification method to support batch verification for multiple owners. Extensive security, performance analysis and experimental results show that our scheme is efficient and secure in multi-cloud.

  • Grey neural network prediction model based on fruit fly optimisation algorithm and its application   Order a copy of this article
    by Yang Jing, Zeng Hui, Huang Jiangping 
    Abstract: The vinyl acetate (VAC) polymerisation rate is considered as an important quality index in the production of polyvinyl alcohol. However, the quality of polyvinyl alcohol can not be controlled effectively because it can not be measured online. Therefore, how to design reliable estimation of VAC polymerisation rate is crucial. The fruit fly optimisation algorithm (FOA), as a novel meta-heuristic and evolutional algorithm, has several merits, such as higher prediction accuracy, having few parameters to be adjusted and able to achieve global optimum. This paper proposes a grey neural network prediction model to improve the prediction performance by taking advantage of FOA to optimise the 'whitening' parameters of this grey neural network. Based on the data from a real plant, the proposed grey neural network prediction model combined with FOA (FOA_GNN) is evaluated and proved to be valid. Its simulation experimental results also confirm the advantage of FOA_GNN algorithm to the traditional grey neural network model (GNN), the adaptive compete genetic neural network prediction model (ACGA) and radial basic function (RBF) neural network model.

    by Jianhong Zhang, Xubing Zhao, Weina Zhen 
    Abstract: Cloud storage is an important service of cloud computing, it can offer services for data owners in a pay-as-you-go fashion. In cloud storage, after data files are outsourced, data owner no longer has physical controls over the storage. To protect the outsourced data in cloud storage against corruptions, several public auditing schemes for data integrity checking were proposed to achieve data integrity checking. The existing auditing schemes make the auditor execute high computation to check data integrity. It might become a burden for a lot of data owner. To solve the above problem, we propose a novel public auditing scheme with public verifiability and constant communication cost based on self-certified signature scheme in this paper. Thorough analysis shows that our proposed scheme is secure and efficient. The security of our scheme is based on the fixed inversion (FI) problem of the bilinear map and the inversion of hash function. Finally, based on the above protocol, we extend it into multi-user setting.

The automated system called backing technique method is introduced, in which proficient performance administration and simplified constitution are guaranteed. But, in the proposed technique, the concept of backing method is presented with additional features, which, persuades the structure so that intricacy diminution is made feasible. Analysis shows that malfunction of Exe, Win-x, kernel, and host can be detrimental for an individual virtual machine. On the basis of this, a new algorithm is developed called backing algorithm which is one of the finest in its concert. The backing algorithm is intelligent to afford continuous monitoring and can accomplish failure reporting proficiently. In addition to backing algorithm concept, we extensively build virtual machine solution provider (VMSP) to sustain this system by frequent monitoring using virtual machine monitor (VMM).

    Abstract: There is growing interest to replace traditional servers with low power systems. ARM has released new architecture with hardware virtualisation extension support. However, the performance of virtualisation on ARM-based low power platform is unclear. In this paper, a number of performance measurements on basic operations such as disk speed, CPU, memory and network throughput were done on a dual-core ARM Cortex-A7-based hardware platform with two popular open source hypervisor software, Xen and KVM. Basic benchmarks and three popular applications are measured to make a comparison between virtual machine and native machine. Our result shows that the average performance overhead of Xen and KVM virtual machine is between 3% and 4% when the host is lightly loaded, while the performance of three applications drops drastically with the workload stress increase in the system. The IO virtualisation should be optimised for the industrial usage of ARM-based virtualisation server.

    Abstract: Decision tree, as one of the most widely used methods in data mining, has been used in many realistic applications. Incremental decision tree handles streaming data scenario that is applicable for big data analysis. However, imperfect data are unavoidable in real-world applications. Studying the state-of-art incremental decision tree induction using Hoeffding bound, we investigated the influence of imperfect data on decision tree model. Additionally, we found the imperfect data worsen the performance of decision tree learning, resulting in worse accuracy and more consumed resource. This paper would be good reference for the future research. When thinking of a new generation of incremental decision tree, we should try to overcome the negative effects of imperfect data.

    Abstract: It is very necessary to build the integrity of the oil and gas transport pipe network in the steady development of the oil and gas industry. There are a lot of oil and gas pipelines have been in service for more than two decades in China, which means a big security risk. Pipeline leak is a typical example of security incidents. Therefore, the establishment of a system of effective detection pipeline leak will be a priority. We propose fibre Bragg grating (FBG)-based optical fibre sensors for detecting pipeline leakage in oil and gas transportation systems. By placing a sensor on each end of a pipe, the velocity and position of the pipeline leakage can be detected through a series of calculations on the correlation analysis, the time difference, and the characteristics of surface waves. We improve the sensitivity and the accuracy of positioning for the FBG-based optical fibre sensors by enhancing the FBG strain response sensitivity.

    Abstract: High availability is a key non-functional requirement that software and telecom service providers strive to achieve. With the ongoing shift to cloud computing, the challenges of satisfying the high availability requirement become more arduous, as the cloud introduces additional features, such as on-demand access, scalability, virtualisation, which add to the complexity of the high availability solution. In this article, we target the issue of achieving high availability for the software applications running in the cloud. We first benchmark two of the most prominent middleware implementations for HA. We then build on the most responsive one to present our solution to address the complexity issue of applications high availability deployed in the cloud. Finally, we discuss a quantitative and qualitative assessment of the overhead of our proposed solution.

    by Guoqiang Gao, Ruixuan Li, Zhiyong Xu 
    Abstract: In order to access sensitive documents shared over government, army and enterprise intranets, users rely on an indexing facility where they can quickly locate relevant documents they are allowed to access: 1) without leaking information about the remaining documents; 2) with a balanced load on the index servers. To address this problem, we propose Mimir, a distributed cipher retrieval system for sensitive documents. Mimir constructs the distributed indexes based on load balanced term distribution for better search efficiency and load balanced query. Mimir utilises encryption with random key, partial key update to protect sensitive data and improve query efficiency. Our experiments show that Mimir can effectively protect secret data and answer queries nearly as fast as an ordinary inverted index.

  • A New Multi-Criteria Decision Process to Prioritize Requirements   Order a copy of this article
    by Amroune Mohamed, Zarour Nacereddine, Charrel Pierre Jean 
    Abstract: Most software projects have more candidate requirements than can be realized within the time and cost constraints. Prioritization helps to identify the most valuable requirements from this set by distinguishing the critical few from the trivial. However, many studies showed that requirements prioritization is still an ambiguous concept and current practices in the companies are informal. This paper presents a novel multi-criteria decision analysis process to prioritize requirements.rnrnThe novelty of the presented idea is three-fold. Firstly, to prioritize requirements, it distinguishes two categories of requirements according to their level of abstraction: low-level requirements and high-level requirements, i.e. business goals. Then, it relates business goals to the requirements of low-level which contribute to their fulfillment. This will improve the completeness and traceability of requirements. Secondly, requirements prioritization is based on their degree of contribution to the identified business goals and their importance. So, business goals become the evaluation criteria. Finally, this process takes into account relationships and dependencies that may exist between business goals. At this end, we employ Analytic Hierarchy Process (AHP) method to give weights to business goals and Choquet integral to calculate a global score, i.e. priority, for requirements. A case study is presented to illustrate the applicability of this process and the effectiveness of using the fuzzy Choquet integral and AHP method.

  • Modeling UML State Machines with FoCaLiZe   Order a copy of this article
    by Messaoud Abbas, Choukri-Bey Ben-Yelles, Renaud Rioboo 
    Abstract: UML and OCL are largely adopted as a standard to describe the static and the dynamic aspects of systems and to specify their properties. Model Driven Engineering (MDE) techniques can be used to automatically generate code from such models. For critical systems, formal methods are frequently used together with UML/OCL models in order to analyze and check model properties. In this paper we propose a combination of UML/OCL and FoCaLiZe, an object-oriented development environment using a proof-based formal approach. More specifically, we propose a formal transformation of UML state machines conditioned with OCL constraints into FoCaLiZe specifications, that can be refined to generate executable code. The proposed transformation supports communication between a class structure and its state machine. Thanks to Zenon, the automatic theorem prover of FoCaLiZe, errors of the original UML/OCL model, if any, are automatically detected. We illustrate our translation with a concrete case study.
    Keywords: FoCaLiZe; UML; OCL; state machine; MDE; proof; Coq; Zenon.

  • Remote sensing image retrieval using object based, semantic ,classifier Techniques   Order a copy of this article
    by Suresh Kumar Nagarajan, Arun Manoharan 
    Abstract: Data captured by satellites is increasing exponentially for agriculture and crop management, health, climate changes and future prediction of plants. Now a days it is required to have reliable, automated, satellite image classification and recovering system. Every day there is a massive amount of remotely-sensed data being collected and sent by satellite. Many retrieval systems are proposed for image content and information retrieval. However, the output of these approaches is generally not up to expectation. In this paper presents a new approach, remote sensing image retrieval scheme by content base image retrieval with grid computing and advanced database concept and this will speed up both input processing and system response time. This paper presents the idea of the parallel processing of input data, queries, and storing images in the database using advanced database concept like B+ or BST trees.
    Keywords: 2-D MHMM ( Two-Dimensional Multi-resolution Hidden Markov Model); Remote Sensing Images; and Semantic network.

  • An Empirical Study of clone detection in MATLAB/Simulink Models   Order a copy of this article
    by Dhavleesh Rattan, Rajesh Bhatia, Maninder Singh 
    Abstract: Complex systems consisting of millions of components are very difficult to develop and manage. Thus model driven development has become an essential development paradigm. But very large scale models suffer from unexpected overlaps of parts. The overlapped and copied fragments in models are known as model clones which increase maintenance cost and resource requirements. Recent research has shown the presence of clones in MATLAB/Simulink models. To gain better understanding, we have conducted an in-depth empirical study on 18 MATLAB/Simulink models using ConQAT, an open source clone detection framework. Our study shows that there is a significant cloning in models and find out some interesting patterns of clones which are significant to improve maintenance.
    Keywords: model clone detection; empirical study; software maintenance; matlab simulink models; ConQAT.

  • Intuitionistic Fuzzy Local Binary Pattern for Features Extraction   Order a copy of this article
    by Mohd Dilshad Ansari, Satya Prakash Ghrera 
    Abstract: We propose a novel intuitionistic fuzzy feature extraction method to encode local texture. The proposed method extends the fuzzy local binary pattern approach by incorporating intuitionistic fuzzy set theory in the representation of local patterns of texture in images. Intuitionistic fuzzy local binary pattern also contribute to more than one bin in the distribution of the intuitionistic fuzzy local binary pattern values which can be used as a feature vector. The proposed intuitionistic fuzzy local binary pattern approach was experimentally evaluated for Lena image of the size 256*256. The results validate the effectiveness of the proposed intuitionistic fuzzy local binary pattern over the local binary pattern and fuzzy local binary pattern feature extraction methods.

  • Swarm intelligence algorithms in cryptanalysis of Simple Feistel Ciphers   Order a copy of this article
    by Tahar Mekhaznia, Abdelmadjid Zidani 
    Abstract: Recent cryptosystems constitute a hard task for cryptanalysis algorithms due to the nonlinearity of their structure. This problem can be formulated as NP-Hard. It has long been subject to various attacks; related results remain insufficient especially when handling wide instances due to resources requirement which increase with the size of the problem. On another side, heuristic optimization methods are techniques able to investigate large spaces of candidate solutions. Swarm intelligence algorithms, part of heuristic methods represent a set of approaches characterized by their fast convergence and easy implementation. The purpose of this paper is to provide, and for a first time, a detailed study about the performance of two swarm intelligence algorithms, BAT algorithm and Wolf Pack Search Algorithm (WPS) for cryptanalysis of some variant of Feistel ciphers. Experiments were accomplished in order to study the effectiveness of such algorithms in solving the considered problem. Moreover, a comparison of VMMAS, PSO and DE algorithms establishes this advantage
