    by Zhenghua Xin, Ma Lu, Guolong Chen, Hong Li, Qixiang Song, Meng Xiao 
    Abstract: Consumers wish fish poles to have high quality, diverse functions and personalization. This intelligent float mainly focuses on its functions. Compared with the existing fish poles products, it can fish at night. Because it has the night light. When the floats are put into the river, lake or the sea, the LED light will flash and the green light is easy to recognize. This fish pole can make fish more accurate. And anglers enjoy themselves. This fish pole also has the accelerometer sensor. When the float is pulled by the fish in the water suddenly, the acceleration generates. It makes the light turn into the red. It prompts there are fish on a hook. It is especially convenient for us to use in the evening. Now, the intelligent telephone is very important for people to communicate with others. When the fish bites food on hooks, the SMS will send to the telephone. It tells people to take up the rod line. We deliberately designed the Bluetooth module linked with the floats. So that we play with mobile phones and fish simultaneously. When fish bite the food on the hook, the line triggers the infrared sensor. And then the SMS which content is get fish generates and sends to the angler. The designed alarm works automatically to make anglers enjoy the game. Similarly, the shocked float triggers the infrared sensor and the buzzer works to remind the angler.

    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.

  • Low-Complexity LDPC-Convolutional Codes based on Cyclically Shifted Identity Matrices   Order a copy of this article
    by Fotios Gioulekas, Constantinos Petrou, Athanasios Vgenis, Michael Birbas 
    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 standards for wireless and wireline telecommunications, respectively.

  • Wi-Fi Received Signal Strength Based Hyperbolic Location Estimation for Indoor Positioning Systems   Order a copy of this article
    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.

  • Suboptimal Joint User Equipment Pairing and Power Control for Device-to-Device Communications Underlaying Cellular Networks   Order a copy of this article
    by Chaoping Guo, Xiaoyan Li, Wei Li, Hongyang Li 
    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.

    Abstract: The terrain pretreatment based on image processing in the Yazidang Reservoir is presented. The image processing is based on the image stitching and the image edge detection. The SURF algorithm is used to extract feature points of reservoir partial images. To match feature points and stitch reservoir partial images, the wide view reservoir image is stitching using KD-tree algorithm and linear gradient fusion algorithm. The improved mathematical morphology is adopted, and five different shapes and four different scales of structural elements is implemented to obtain precise waterfront edge of reservoir image. The *.dxf file is obtained by using CAD software to depict reservoir shore contours. It transforms *.dxf into *.kml to extract latitude and longitude information of reservoir waterfront edge. The satisfied mesh effect is generated by using the Delaunay triangulation algorithm.The result shows that accurate and detailed reservoir terrain can be obtained using the image processing method and the GE software, which provides a prerequisite for the numerical simulation of sedimentation in the Yazidang Reservoir.

    Abstract: The classification of imbalanced data can increase the comprehensibility and expansibility of data and improve the efficiency of data classification. The accuracy of classification is poor when the data is classified by the current method for imbalanced data analysis of big data. To this end, this paper presents an imbalanced data classification algorithm based on fuzzy rule. The algorithm firstly collects the imbalanced data, selects the features of the imbalanced data, and optimizes the imbalanced data classification algorithm by using the fuzzy rule classification algorithm..The experimental results show that when the classifier maintains a certain size of the weak classifier, the classification accuracy of the proposed algorithm will be gradually improved as the training time increases, and gradually be stable within a certain range of accuracy, this method can improve the accuracy of imbalanced data classification.

  • 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.

  • 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.

    by Yajun Zhang, Yawei Chen, Hongjun Wang, Meng Liu, Liang Ma 
    Abstract: Device-free passive localization (DFL) has shown great potentials to localizing target(s) without carrying any device in the area of interests (AoI). It is especially useful for many applications, such as hostage rescuing, wildlife monitoring, elder care, intrusion detection, etc. Current RSS (received signal strength) based DFL approaches, however, can only identify underlying the prerequisite that the signal collected is mainly conveying along a direct line-of-sight (LOS) path, but cannot perform well in a typical indoor building with multipath effects. This paper explains the fine-grained CSI-based localization system that is effective to locate within multipath environment and non-line-of-sight scenarios. The intuition underlying our design is that CSI (Channel State Information) benefits from the multipath effect, because the received signal measurements at different sampling positions will be the combination of different CSI measurements. We adapt the improved maximum likelihood method to pinpoint single target's location. Final, we propose a prototype of our design utilizing commercial IEEE 802.11n NICs. Results from the experimental scenes of a Lobby and a laboratory of our university, comparing to RSS-based and CSI-based scheme, demonstrate that our design can locate best single target with the accuracy of 0.95m.

    by Ding Yuan, Chuanbao Du, Houde QUAN 
    Abstract: This paper analyses the performance of distributed transmit beamforming in presence of oscillator phase noise. Average beampattern of arbitrary array is adopted here as performance index. In the analysis, the phase noise process of each node oscillator is described by a stationary model taking into account and shape single-sideband (SSB) spectrum. By using non-parametric kernel method, the average beampattern in presence of phase noise is derived and corresponding beampattern characteristics are evaluated. Theoretical analysis and simulation results show that the accumulated PN can result in the degradation of DTBF performance, which are also reflected in the change of beampattern characteristics, such as 3dB width, 3dB sidelobe region and average directivity. With the increase of time duration, the cumulative phase noise becomes greater, and the degradation is more obvious.

  • A 3D model retrieval method based on multi-feature fusion   Order a copy of this article
    by Hong Tu 
    Abstract: 3D model retrieval is a hot topic in information retrieval, and it is of great importance to fuse multi-feature of 3D models to achieve high quality retrieval. Therefore, in this paper, we propose a novel 3D model retrieval method based on the multi-feature fusion technology. Motivation for the proposed 3D model retrieval method lies in that we convert the 3D model retrieval problem to a discriminative feature space mapping problem. The framework of the multi-feature fusion based 3D model retrieval system contains two main modules: 1) model normalization, and 2) multi-feature fusion. The proposed 3D model retrieval method is designed based on multiple feature fusion and online projection learning. In order to effectively fuse multiple features, we train a model to learn a low dimensional and discriminative feature space from the multiple views of 3D models. Particularly, to effectively retrieve the newly added samples, we propose an online projection learning algorithm, which learns a projection matrix by handling the least square regression model. Experimental results show that the proposed method can achieve higher precision for a given recall than others methods, that is, the proposed method can obtain higher quality 3D model retrieval results than state-of-the-art methods.

But as ATM expanded its reach into human life, crimes related to ATM theft and fraud increased exponentially. There are flaws related to ATM security which is exploited by the criminals. ATM card cloning, card skimming, ATM pin theft are a few of the most common crimes related to the ATM. These crimes result in loss of money measured in billions. The newspapers are full of these crime reports and hacks. In this paper, we have proposed an automated random color keypad by which ATM security can be enhanced; making these ATM attacks and fraud very difficult.

    Abstract: This paper presents a fault-tolerant algorithm ensuring multiple resources sharing in Mobile Adhoc Networks (MANETs) that is able to handle the known k-mutual exclusion problem in such mobile environments. The proposed algorithm relies on a token-based strategy, and requires information about resources and their use to be carried in routing protocol control messages. This way, our solution avoids any additional exchange of messages. Furthermore, experimental results show that it offers a fast response time. Moreover, we introduce a dual-layer fault-tolerance mechanism that tolerates the faults of several sites at the same time without affecting the well functioning of the system. Simulation results also evidence the high efficiency of our proposal, which achieves reduced overhead and response delay even in the presence of critical situations where multiple simultaneous faults occur.

  • 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.

    Abstract: VANET is a vehicular ad hoc network, which is highly dynamic, self-organised 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 decentralised 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.

    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 colour (red, green and blue) of a RGB LED are utilised for transmission, thus giving a total of nine channels. Colour filters (CFs) and selection combining (SC) are also utilised 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.

    by Hong Min, Jinman Jung, Junyoung Heo 
    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 synchronisation 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.

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.

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.

    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 centralised 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 realise 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.

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.

    by Liang Zong, Wencai Du, Yong Bai 
    Abstract: The mechanical vibration monitoring system based on the cable connection has characteristics such as the complexity of the cabling layout, high cost and poor maintainability and system flexibility. This paper introduces wireless sensor network (WSN) into the mechanical vibration monitoring. The monitoring data transmission in the wireless sensor network is completed by radio waves. There are significant advantages that low cost, remote monitoring, facilitates the diagnosis and maintenance. The multi-hop function and topological flexibility of WSN can effectively avoid wireless signal attenuation effect of buildings and equipment. This paper presents a wireless sensor network model for the mechanical vibration monitoring, analyses the two kinds of wireless sensor network topology, and sets up a vibration sensor monitoring network system. The system takes vehicle vibration sensors to collect monitoring data, and combines the ADTCP algorithm for multi-hops network, puts forward a scheme that limits the congestion window to reduce the network congestion. In this paper, the scheme can effectively alleviate the sink node's congestion in the mechanical vibration monitoring wireless sensor network, and improve the performance of network monitoring.

    by Karima Djebaili, Lamine Melkemi 
    Abstract: In this paper, we propose a new and practical variant of ElGamal encryption which is secure against every passive and active adversary. Under the hardiness of the decisional Diffie-Hellman assumption, we can prove that the proposed scheme is secure against an adaptive chosen ciphertext attacks in the standard model. Such security verifies not only the confidentiality but also verifies the integrity and the authentication of communications. We display that the modified scheme furthermore achieves anonymity as well as strong robustness.

  • Sybil attack resistant location privacy in VANET   Order a copy of this article
    by Allam Balaram, S. Pushpa 
    Abstract: Vehicular ad hoc networks (VANETs) are more susceptible to Sybil attack where a malicious vehicle compromises a road side unit (RSU) and behaves as multiple vehicles. Thus, an efficient mechanism is essential to identify the attacker, compromised RSU, and location privacy of anonymous vehicles. This paper proposes a Sybil attack resistant location privacy (SARLP) system to identify the attacker even when a compromised RSU is present in the VANET. The SARLP system employs a location privacy unit (LPU) and provides a robust authentication mechanism. A secret random number verification at the interference range of two RSUs identifies the compromised RSU. The SARLP system efficiently provides complete location privacy to the vehicles against Sybil attack. The simulation results show that the SARLP system achieves a high level of location privacy of vehicles and attack resilience compared to the existing footprint scheme.

  • A variant of random way point mobility model to improve routing in wireless sensor networks   Order a copy of this article
    by Lyamine Guezouli, Kamel Barka, Souheila Bouam, Abdelmadjid Zidani 
    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 maximise the coverage radius of the base station (which will be fixed in our study) and thus to optimise the data delivery end-to-end delay.

    by Sourour Trab, Ahmed Zouinkhi, Eddy Bajic, Mohamed Naceur Abdelkrim, Hassen Chekir 
    Abstract: This paper relies on the concepts and architecture of IoT to design a risk monitoring system for a hazardous product warehouse. The enhancement of product into smart product as a sensor-equipped communicating device allows controlling and monitoring the product interactions in the objective of risks prevention and avoidance. A generic warehouse safety policy supported by the smart products is presented that relies on a set of parametric safety rules for storage, picking and handling of products. Our proposal aims to provide the benefits of information availability, communication and decision-making, deep in the warehousing physical world, and oriented toward a global safety assurance. We present an implementation case for chemical products warehousing, that uses ZigBee wireless sensor network platform and LabView software. The achievement of smart products and remote monitoring allows dynamic risk assessment by analysis of product's information and status, and ambient condition parameters of warehouse for safety assurance.

  • The study of access point outdoor coverage deployment for wireless digital campus network   Order a copy of this article
    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.

  • Feature-opinion pair identification method in two-stage based on dependency constraints   Order a copy of this article
    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%.

  • Design and realisation of a wireless data acquisition system for vibration measurements   Order a copy of this article
    by Surgwon Sohn, Suhee Kim 
    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. The proposed wireless DAQ system is based on the TMS320 digital signal processor which enables us to process real-time vibration signals. Sensitivity is one of the key performance features in the DAQ system, and we use an integrated circuit piezoelectric (ICP) accelerometer as a detection sensor for best performance. For faster wireless transmission of large amount of acceleration signals, a new data link protocol of Bluetooth interface between wireless DAQ and smartphone is proposed. An Android smartphone is a good choice of user interface in the mobile data acquisition system. In order to display vibration signals in real time at the Android smartphone, a commercial Java graphic library tool is used.

  • Weighted estimation for texture analysis based on Fisher discriminative analysis   Order a copy of this article
    by Xiaoping Jiang, Chuyu Guo, Hua Zhang, Chenghua Li 
    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 (WETA) method based on the Fisher discriminative analysis (FDA) is proposed. First, local binary pattern (local binary pattern, LBP) or partial phase quantisation (local phase quantisation, 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 optimisation is given. Finally, experiments on two major general face databases (FERET and FEI) verify the effectiveness of the proposed method. The proposed method receives a recognition rate of 96% in LPQ and FERET combination. The experimental results show that compared with texture methods in other papers, the proposed method in this paper has obtained better recognition performance.

    by Xiaohong Zhang, Juan Lu 
    Abstract: A new lightweight RFID mutual authentication protocol which the security keys updated dynamically is presented by using cyclic redundancy check code (CRC code) operations and some simple logic operations. GNY logic proof and security analysis show that the protocol not only achieve the mutual authentication requirements effectively between the readers and the tags, but also prevent many security privacy problems such as eavesdropping attack, replay attack, replication attack, the problem of tag tracking on the basis of without increasing computation and communication traffic of the RFID system. Especially, the new protocol meets the EPC Class1 Gen2 standard, compared with the same safety degree of other existing protocols, the new protocol is low complexity in the aspect of hardware implementation which consumes only 18.75% of the reserved space in terms of label storage and it is suitable for low-cost RFID system. Hence, the new protocol can realise the combination of high security and low tag cost.

  • Experimental study on fibre Bragg grating temperature sensor and its pressure sensitivity   Order a copy of this article
    by Deng-pan Zhang, Jin Wang, Yong-jie Wang 
    Abstract: At present, ocean temperature almost depends on electric signal inspection, but the sensor is not safe in the water. In order to overcome this shortage and improve measurement veracity and safety, the temperature sensing theory of Bragg grating was analysed and a new ocean temperature sensor was presented with advantages of all optic elements, underwater safety and feasibility of sensor network, etc. By setting a spring in the metal tube, the temperature was measured with pressure isolation encapsulation. Multiple plus-minus temperature tests were carried out. Results show that the sensor under the condition of no pressure and the temperature of 0~35°C has an excellent repeatability, hysteresis and linearity. Temperature sensitivity is 29.9 pm/°C, which is close to the theoretical value. Pressure sensitivity tests were executed under the condition of 0~5 MPa. Results show that the wavelength has no change and is not affected by pressure.
