| Abstract: | Wireless sensor network(WSN)is known as one of the three major techniques in 21st century,and its security issues have received much attention.This article presents the characteristics of wireless sensor networks,analyzes the roots of the security issues,and then describes in detail the theory of wormhole attack and its destructions.In this paper,the simplified Marsh model is introduced too.By gathering data from the events of neighbor nodes the node can evaluate the trustiness of its neighbor.Through concr... |
