A Power Efficient Method to Prevent Sybil Attack in Wireless Sensor Network

Abstract - Security is important for many sensor network applications. A particularly harmful attack against sensor and ad hoc networks is known as the Sybil attack , where a node illegitimately claims multiple identities. In a Sybil attack, a malicious user obtains multiple fake identities and pretends to be multiple, distinct nodes in the system. The attacks occur during interactions between the trading peers as a transaction takes place. In this paper we are creating a powerful centralized authority Global Inspector and powers are given to that so that it can identify the Sybil attack by SybilTrust mechanism. The paper based on internal attack in the network. Transmission should be through the GI only. We also show the impact of the attack through an example and simulation results. The algorithm is implemented in Network Simulator.
