A Security Detection Scheme Based on Evidence Nodes in Wireless Sensor Networks

Node Duplication Attacks could directly damage sensor nodes, and have strong destruction to seriously impact on Wireless Sensor Networks. Against such attacks, this paper presents an improved detection method of node duplication attacks. The network is organized into clusters based on the LEACH algorithm. The level of trust is determined regularly by threshold computation, and then nodes choose to receive or reject the data by their levels of trust. Nodes within the cluster can effectively detect the node duplication attacks based on evidence nodes. Simulation results show that this method can improve the detection efficiency of node duplication, and compared with the traditional methods, it coats low energy and transport.
