  • Simulation Research of Nodes Target Tracking Algorithm Based on Clustering in Wireless Sensor Network   Order a copy of this article
    by Kaibin Wei 
    Abstract: Since sensor nodes are constrained in cost and volume, they have limited ability in data storage and processing. Therefore, the routing algorithm needs lower time and space complexity for energy conservation. This article design a dynamic cluster head selection mechanism based on backoff time of residual energy of nodes, aiming at energy conservation and low complexity for the algorithm. At the phase of cluster head selection, we reduce the backoff time of nodes with more energy, so it can win the competition in cluster head selection and control the number of cluster heads, by controlling the radius of cluster lead broadcasting. Then the cluster member nodes are chosen according to the hop range to cluster head, whose weights are computed by the distance to cluster head and the residual energy. At the premise of saving self-energy, it can choose different cluster head and save the energy of cluster head to achieve global energy balance and prolong the network lifetime. The simulations verify that the improved algorithm can make reasonable distribution location of cluster head. The membership has close number and the reasonable topology ensure the global consumption of network.

  • CRAM: Clustering-based Resource Availability Measurement in Mobile Peer-to-Peer Systems   Order a copy of this article
    by Moufida Rahmani, Mahfoud Benchaiba 
    Abstract: The peer-to-peer (P2P) systems are an alternative to solve the scalability issue raised by the client/server systems. P2P systems are composed of a set of entities that communicate directly without any central server and constitute scalable and robust distributed systems. In these systems, an entity only has a partial knowledge about the overlay state. The challenge is to provide a global knowledge in the system regarding a feature as the resources availability. In this paper, we propose a Clustering-based Resource Availability Measurement called CRAM for mobile P2P networks which relies on knowledge from all entities. CRAM can be used in resource search and in replication strategies to improve the network performances. Simulation results show that our estimation of availability is close to the real one such as the deviation between them can equal 0.008. They also show that our algorithm reacts efficiently to the appearance or depletion of a resource replica in the system.

  • Structural Optimization Algorithm of Weight Correlation Analysis for DBN   Order a copy of this article
    by Min Zhang 
    Abstract: The Deep Belief Network (DBN) algorithm has slow convergence rate and low learning efficiency, and it is sensitive to model hyperparameters. In view of the fact that DBN is a learning network model with a large number of network nodes and multiple hidden layers, this paper proposes a weight correlation analysis algorithm for DBN (WCA-DBN) to determine the approximately optimal network structure of DBN. This algorithm establishes a PS orthogonal projection space based on the arbitrary node set using the Linear Discriminant Analysis (LDA) method, projects the balanced node set onto the PS plane, and solves the weights of the network nodes between sets through the correlation principle, to adjust the network structure of the hidden layer adaptively. The real-time traffic flow of six different types of roads in Jinan City, Shandong Province was selected as experimental materials to verify that the WCA-DBN algorithm has more obvious advantages over traditional algorithms in terms of accuracy and time complexity.

    Abstract: In recent years, researchers have proposed a number of encryption algorithms and encryption schemes to protect the privacy of individuals or businesses. However, these encryption algorithms and encryption schemes are difficult to achieve a certain balance in term of encryption efficiency and security. In order to achieve this goal as much as possible, we propose a hybrid encryption technique, which makes the best use of two encryption techniques to achieve higher security and faster speed of encryption algorithm. We introduce two techniques in this hybrid encryption scheme. The first is scrambling and the second is encryption. We evaluated the performance of encrypted video by comparing the PSNR and SSIM values of the scrambled video and the encrypted video. Experimental results show that the proposed scheme has high encryption efficiency and good security.

    by Zhichao Wang, Liang Tang, Jun Steed Huang, HongWei Shi, Li Bian 
    Abstract: For smart street light wireless sensor networks, there are huge amount of redundant packets flooding in the route discovery process, resulting in information explosion and high energy consumption. To solve these problems, this paper proposes an improved flooding routing protocol which is suitable for smart street light wireless sensor networks. The protocol can receive signals which include the serial number of copies of the packets, destination address, node types and so on, and it determines the received signal whether need to be forwarded again or not. It forward signal according to a probability which is selected from Golden Ratio (GR), Moon Age (MA), Lunar Month (LM), Euler-Mascheroni constant (EM), EmbreeFrefethen constant (EF), LandauRamanujan constant (LR), Prime Quadruplet (PQ) based on the environment factors such as the season. Thus the protocol can prevent the information explosion effectively and reduce the energy consumption of the entire network, while without lowering the reliability. Through the practical application test analysis, combined with Matlab simulation, we show that the improved algorithm can balance the efficiency versus the reliability, and it has a very broad application prospects.

    by Sasikala Chinthakunta, Shoba Bindu Chigarapalle 
    Abstract: Cloud storage provides flexible On-demand data storage services to users at anytime and anywhere. However, this new model of data storage introduces a number of new security threats in Cloud Computing environment, because of the loss of physical control over the outsourced data. One of the major challenging issues is data integrity protection. To address this problem several Remote Data Integrity Checking (RDIC) protocols have been proposed, but most of them do not support batch verification, or they rely on Public Key Infrastructure. In this work, we introduce a Certificateless Batch Verification Protocol using Lattices, which supports data integrity checking of multiple data files in a multi-cloud environment. Using, this protocol Third Party Auditor (TPA) can check the data integrity of the multiple data files stored on different cloud service providers at a time. By utilizing, random masking technique and Fibonacci based search approach the proposed protocol not only provides privacy preserving RDIC but also achieves rapid identification of the corrupted data. With this batch verification, we will reduce the computation overhead and communication overhead over the TPA. Through a security analysis we prove the storage correctness and privacy against the TPA of the proposed method. And the experimental results shows that the proposed batch verification decreases computation cost over the TPA approximately 10% compared to the individual verification.

  • A Low Cost Paging Scheme for Clustered PMIPv6 Protocol by Head-MAG Entity Utilization   Order a copy of this article
    by Adnan Jabir 
    Abstract: Clustered PMIPv6 (CPMIPv6) was proposed to reduce the PMIPv6 signaling cost by dividing the domain into clusters each with a Head-MAG used to control the intra-cluster operations. However, existing mobility protocols perform registration process even for idle nodes, which leads to degrade the protocol performance due to unnecessary location updates. On the other hand, paging technique is widely used in cellular networks to reduce the signaling required for idle nodes registration. Although several paging schemes were proposed to enhance the PMIPv6 performance, they are either based on central entity or they incur high signaling cost due to multicasting. Inspired by CPMIPv6 architecture, this paper proposes a low cost paging scheme where each cluster is considered as a paging area and Head-MAGs entities are utilized to perform the paging functions within the cluster. The analytical results show that the proposed scheme outperforms the existing paging schemes in terms of paging signaling cost.

    Abstract: Data feature extraction is vulnerable to external interferences during traditional classification of associated data of large-scale network system, resulting in low classification accuracy and large time consumption, so an optimized classification algorithm of large-scale network system associated data features based on deep learning is proposed. In this algorithm, associated data of large-scale network system is acquired through the multi-sensor quantization fusion method, and the acquired data is done with spectral decomposition to obtain the convergence conditions for feature components of associated data of large-scale network system; then the feature components are processed based on a spectrum analysis model to extract features of associated data of large-scale network system; the features of the associated data are done with piecewise regression analysis, and data samples are output in classification based on the deep learning algorithm. Simulation results show that the proposed method can accurately classify associated data with relatively short learning steps with accuracy 24.7% higher than that of the ARMA classification method and 22.6% higher than that of the decision tree classification method.

  • Delay and Jitter Sensitivity Analysis with varying TCP fraction for Multiplexed Internet Communications   Order a copy of this article
    by Sneha Thombre, Lalit Patnaik, Anil Tavildar 
    Abstract: Queuing delay and Jitter are much more difficult to evaluate as all other components of end-to-end delay are adequately characterized in Internet. Jitter is particularly important to manage the QoS of real-time applications. Queuing delay and jitter are clearly related to congestion control and occur at the network layer, therefore the queuing delay and jitter are analyzed at the network layer in this paper. Initially, arrival and service processes for multiplexed TCP and UDP datagrams at the congested router output queue are modeled. The model accounts for the fraction of TCP and UDP datagrams (as they contend for resources), the arrival and service distributions of TCP and UDP with their respective datagram sizes. Mean queuing delay, average instantaneous queuing delay and jitter are quantified using queuing theory and the arrival and service process model. The findings of the analysis are then compared with NS2 simulation results. The interesting and intriguing result is that, delay related performance of the tagged flow is adversely affected by the fraction of TCP in the background traffic. This is particularly important because TCP dominates the overall traffic. The simulation results fairly agree with the analytical values. The conclusion is true for Cubic, Reno and Compound TCP flavors.

The improved genetic algorithm is used to solve the model and obtain the optimal scheduling scheme. The experimental results show that the traffic capacity of the proposed method varies from 0 to 1.0, which can ensure the smooth traffic of the vehicle. When the traffic congestion is light, the vehicle throughput of the three scheduling models is not significantly different. In the case of congestion and heavy congestion, the throughput of the proposed method is always in the range of 0.4-0.8, and the scheduling performance is the best.

    by Xiaohai Lan 
    Abstract: The existing technology can not meet the needs of large data network security index measurement in the era of big data. New theories and methods need to be explored to support the application of large data. In this paper, an improved second-order cone programming model (MTOCPM) is used as the data expression vector.

    by Zheng Ma, Yan Ma, Xiaohong Huang, Manjun Zhang, Bo Su, Liang Zhao 
    Abstract: Aiming at the traditional on-demand scheduling method of routing load, there are many problems, such as long time to complete the total task and high energy consumption. An on-demand scheduling method of routing load based on multiple SINKs is proposed. The total routing load task is sent from multiple SINK nodes to SDN network. After receiving the sub-tasks sent by SINK, the intra-cluster nodes begin to collect network data together. After the cluster heads fuse the network data transmitted by the nodes, the results are sent to SINK nodes. As a result, the shortest total task completion time is obtained, and the shortest total task completion time is used as the objective function of routing load scheduling on demand. Ant colony algorithm is used to solve the problem and complete the scheduling. Experimental results show that the proposed method has shorter completion time and lower energy consumption of total task.

    by Guanlin Chen, Kunlong Zhou, Yubo Peng, Liang Zhou, Yong Zhang 
    Abstract: With the popularity of wireless networks in recent years, the mobile phone users accounted for 95.1% in China. Meanwhile, the security issues cannot be ignored. The cost of wireless attacks is getting lower, and there are more frequent occurrence of wireless fishing, wireless crack and other security events. However, the current traditional intrusion prevention method can only cope with relatively simple attack scenarios. Therefore, the development of new intrusion prevention system is particularly important. In this paper, we design and implement a novel network intrusion prevention system, which uses VpnService and TcpDump to capture traffic as a data source, cooperates with the single-step attack rule signature database and the attack chain signature database to perform real-time intrusion detection, and combines intent analysis to detect intrusion intention-behavior and output alarms. The results show that the system is effective in recognizing typical wireless attacks.

  • A novel Neuro-Fuzzy based localization system for WSN using node proximity   Order a copy of this article
    by Somnath Sinha, Aditi Paul 
    Abstract: Localization is a challenging issue in wireless sensor network. This paper describes a neural network and fuzzy logic based approach for localization in Wireless Sensor Network (WSN). The Received Signal Strength Indicators (RSSIs) of some anchor nodes are used as basic parameter to estimate the location of sensor nodes. Using Fuzzy Logic the RSSI values of anchor nodes are categorized into some predefined regions and RSSI patterns are generated using Fuzzy Inference rules. These patterns are then used as input to a trained Neural Network (NN) for estimating a proximity factor of sensor nodes which in turn is used to calculate their positions. The RSSI patterns are used to find out the weighted position of the anchor nodes which when divided by the proximity factor gives the estimated position of the sensor nodes. A modified back propagation method is used to train the neural network. Proposed model is tested using network simulator NS2 and result shows accuracy up to 95%.

    by Yong Li, Bo Li, Mao Yang 
    Abstract: The next generation wireless local area network (WLAN) needs to significantly improve area throughput in high-dense deployment scenarios. Facing to the interference spread problem of OFDMA MAC, some existing studies introduce spatial clustering group-based OFDMA protocol (SCG-OFDMA), which enables geographically close nodes to send uplink OFDMA data simultaneously. However, SCG-OFDMA assumes that all the nodes have saturated traffic, which cannot be directly extended to the unsaturated traffic case. In this paper, an unsaturated traffic oriented spatial clustering multiusers MAC protocol (SCM-MAC) is proposed. Specifically, spatial clustering multiusers (SCM) discovery process is designed. After that, whether the cluster heads have traffic or not, they contend channel for their group members. Moreover, theoretical analysis of the optimal access radius is derived. Simulation results are in agreement with the theoretical analysis, and show that the area throughput of SCM-MAC is 34% and 50% higher than that of IEEE 802.11ax and OMAX protocol, respectively.
