    Geographical information based false report filtering scheme in wireless sensor networks by Zhi-xiong LIU, Jian-xin WANG

    Published 2012-02-01
    “…A geographical information based false reports filtering scheme(GFFS)in sensor networks was presented.In GFFS,each node distributes its location information to some other nodes after deployment.When a report was generated for an observed event,it must carry not only MACs from t detecting nodes with distinct key partitions,but also locations of these nodes.Each forwarding node checks not only the correctness of the MAC and the locations carried in the report,but also the legitimacy of the locations.Analysis and simulation results demonstrate that GFFS can resist collaborative false data injection attacks and thus can tolerate much more compromised nodes than existing schemes.…”

    Coverage compensation algorithm based on vector algebra in hybrid wireless sensor networks by Ning-ning QIN, Li-xia GUO, Bao-guo XU

    Published 2014-09-01
    “…Aiming at the phenomenon that coverage holes caused by energy depletion coexisted with remaining energy of dormant redundant nodes in hybrid wireless sensor networks(WSN),a coverage compensation algorithm based on vector algebra to repair coverage hole with redundant nodes was presented.This algorithm included both the respective dis-placement amount calculation method of all the redundant nodes which may be involved in compensation and policies of the choice of the best redundant nodes that were selected by hole boundary node on the basis of balancing the remaining energy of nodes.The result shows that this algorithm makes full of energy resources in the premise of complete coverage to repair coverage hole,and has a better performance in both movement distance and movement cost compared with ex-isting COA algorithm.…”

    Time synchronization method for wireless sensor networks based on mobile reference nodes by Yu-qiang ZHANG, Jing-sha HE, Jing XU, Bin ZHAO, Fang-bo CAI

    Published 2015-11-01
    “…Most existing time synchronization methods in wireless sensor networks depend on the existence of one or more fixed reference nodes and on the propagation of synchronization messages in the networks.Thus,they often suffer from the disadvantages of high energy consumption and large cumulative error due to multiple layers of communication.To address such issues,a new time synchronization method based on a mobile reference node and the optimal mobile path is proposed.Firstly,the cellular coverage technique is analyzed to identify the optimal synchronization points.Then,the optimal mobile path with minimal length is designed.Finally,an efficient single hop time synchronize mechanism based on multiple timestamps in the MAC layer is presented.Comparison with other methods shows that the proposed method can achieve both higher synchronization accuracy and lower energy consumption.…”
