Method of Detecting the Sybil Attack Based on Ranging in Wireless Sensor Network

Method of detecting the Sybil attack based on ranging is proposed in this paper. Every node finds out the suspect nodes by checking the neighbor nodes range. The neighbor nodes exchange the information and find out Sybil node. As a result, the method has costs less, no use for high accurate range, but it has extremely precise. It is particularly suitable for the low-cost, lacking resources of wireless sensor network.
