Simulation Research of Nodes Target Tracking Algorithm Based on Clustering in Wireless Sensor Network
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.

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. The power spectral density feature of large data is extracted from a large number of noisy and fuzzy data. The second-order cone programming model of large data information flow is constructed by rough concept lattice method. Combining with the finite convergence of the second-order cone programming model algorithm, the reliability of each clustering sample is measured, and the accurate search of data clustering center is realized. Experiments show that the method based on MTOCPM fusion can not only greatly reduce the communication cost between network nodes, but also improve the global measurement accuracy by about 10%.

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.

A novel Neuro-Fuzzy based localization system for WSN using node proximity
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%.

Unsaturated traffic oriented spatial clustering multiusers MAC protocol for the next generation WLAN
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.

by Simarjeet Kaur, Navdeep Kaur, Kamaljit Singh Bhatia
Abstract: Node localization is the procedure for finding the physical position of the nodes in a Wireless sensor network (WSN). The network performance is enhanced with nodes precise location. DV (Distance Vector) - Hop localization scheme is one of the most successful localization schemes. It executes competently with the assistance of beacon nodes. However, when network is interrupted with Distributed Denial of Service (DDoS) attack then the localization process of DV-Hop scheme is badly affected. This paper has examined the effects of the DDoS attack on the DV-Hop algorithm. So, a mechanism consisting of swarm optimization and machine learning is proposed to guard against DDoS attack. The architecture also designs a novel fitness function for Artificial Bee Colony (ABC). To check the appropriate effectiveness of the proposed fitness function of ABC, Feed Forward Neural Network with Gradient satisfaction is applied. The cross validation architecture further uses Mean Square Error (MSE) for the back propagation model and effectiveness is checked through a regression model as well. The evaluation is done in terms of Localization error and Transmission loss. The simulation results are obtained using Matlab and show the reduction of 33% for localization error and 27% for transmission loss respectively.

by Abdellah NABOU, My Driss LAANAOUI, Mohammed OUZZIF
Abstract: The Optimized Link State Routing (OLSR) protocol is a proactive routing protocol for Mobile Ad hoc Network (MANET), it is more suitable for large and dense mobile networks thanks to its new concept of Multi-Point Relay (MPR) nodes that reduce the overhead of the network, unfortunately the performance of OLSR routing protocol can be affected by various routing attacks. Node Isolation Attack is considered as a DOS (Denial of Service) attack that affects the function of OLSR routing protocols precisely by isolating the victim nodes and hiding them from the network. In this paper, we propose a new method to detect the Node Isolation Attack by using a modified version of the Quality Factor (Q) that is applied in the physical domain in order to calculate the Q of OLSR control messages and detect the attack. The experimental results show that when the attack is launched in the network between 30 and 70 second, our method can detect it without any modification in the algorithm of OLSR protocol.

by Amrit Suman, Chiranjeev Kumar, Preetam Suman
Abstract: The VANET is an autonomous kind of network in which the nodes can create a wireless connection without the control of base stations. In recent years VANET has become a massive point of attraction for researchers because of its unique characteristics that are link failure and frequent changes in topology because of its high mobility. This makes VANET unique from the mobile ad-hoc network. Intelligent transportation that is a part of VANET helps in increasing transportation efficiency, enhancing safety in traffic and, improving the driving experience. Apart from these benefits, Network instability is the main drawback of VANET that reduces network efficiency. Due to various reasons, a high range of security measures required from multiple network attacks to protecting the communication between the vehicular nodes. In this paper, a routing strategy is proposed, which is based on AODV and MAC to enhance the route discovery and to avoid the collision. The proposed routing strategy consists of automatic size adjustment of contention window depending on the network capacity, channel allocation for each node, priority assigning for different types of messages, and security checking for each packet using CRC; all these are based on MAC. Route discovery and table preparation are based on the AODV. The proposed routing protocol (P-Routing) has been implemented in Qualnet 5.0. The results with the performance of C-AODV then compared. The parameters taken for comparison is total byte received, the signal received with error, total packet loss, and throughput. The number of nodes and speeds of nodes kept in variation to create different scenarios. In all cases, the performance of the proposed protocol is better. The results are described with the graphs in the result section.

Position-related Content Acquisition for CCM
by Yanli Li, Xiaonan Wang
Abstract: The content-centric networking (CCN) depends on reverse paths and limited broadcast to achieve content acquisition, but the reverse-path disruption due to node mobility leads to content acquisition failures and flooding results in considerable content acquisition costs. In this paper, we propose a Unicast-based content acquisition scheme for Content-Centric MANET (UCCM) to reduce content acquisition costs and improve success rates. UCCM employs the address-centric unicast instead of the content-centric broadcast to achieve the content acquisition, so the content acquisition cost is lowered. Moreover, a requester acquires the content from the nearest provider in the address-centric unicast way, so the content is returned to a requester based on the requesters address rather than the reverse paths. UCCM is evaluated, and the analysis results show that UCCM reduces the content acquisition cost by nearly 63.8% and improve the success rate by nearly 5.9%.

by Reyhaneh Rabaninejad, Maryam Rajabzadeh
Abstract: In cloud storage services, public auditing mechanisms allow a third party to verify integrity of the outsourced data on behalf of data owners without the need to retrieve data from the cloud server. In some applications, the identity of data users should be kept private from the third party auditor. Oruta, is a privacy preserving public auditing scheme for shared data in the cloud which exploits ring signatures to protect the identity privacy. In this paper, we propose two attacks and demonstrate that the scheme is insecure and a dishonest server can arbitrarily tamper the outsourced data without being detected by the auditor. We also propose a solution to remedy this weakness with the minimum overhead and without losing any desirable features of the scheme. Performance evaluation demonstrate acceptable efficiency of improved scheme in comparison to the original protocol.

With the collaboration of an existing node, an overlay ID will be assigned to new node which is secured by using a public key cryptography. The paper included a complexity and communication overhead analysis to demonstrate the effectiveness of proposed method which maximizes the defence/protection against ID based attacks. Complexity analysis demonstrates the superiority of the proposed method.

by Huawei Wu, Chuan Sun, Yicheng Li, Yong Kuang
Abstract: In order to improve the safety of tunnel support structure, a deformation detection algorithm based on wireless sensor network is proposed. The wireless sensor network nodes were deployed with the randomly distributed autonomous network grid structure, and the deformation force parameters of the support structures of shallow span and large span tunnels were obtained with the pressure sensor, and the power spectrum characteristic quantities of the sensor parameters were extracted. The time-frequency characteristic decomposition method is used to realise the beamforming processing deformation parameters. The quantitative analysis ability of the improved structure deformation is detected according to the detection of deformation amplitude and the estimation of related parameters. The experimental results show that the detection accuracy of the method is improved from 87% to 100%, and the detection performance is improved, which verifies the effectiveness of the method.

Abstract: Aiming at the problems of low detection efficiency and poor clustering effect in traditional abnormal network data mining process, an abnormal data mining model based on kernel extreme learning machine and particle swarm optimisation is proposed. The enhanced local linear embedding algorithm is used to extract the features of abnormal network data, and the required feature dimensions are extracted repeatedly to obtain the corresponding features of target network data. K-means algorithm is introduced to cluster the target network data to increase the identification of data mining. By improving the particle swarm optimisation algorithm to optimise the parameters of the kernel limit learning machine, the final abnormal data mining results are the best. The experimental results show that the proposed method has high detection efficiency and good clustering effect, which fully proves the superiority of the proposed method and lays a foundation for the progress of abnormal network data mining technology.
