Abstract
Wireless ad hoc networking is a technology that allows fast, easy, and inexpensive network deployment. Unfortunately, these advantages also make the task of an attacker simpler, as it is also easier to deploy a malicious node in the environment.. A number of schemes have been proposed, but they differ greatly in the algorithms they use and in the networks upon which they are evaluated. As a result, the research community lacks a clear understanding of how these schemes compare against each other, how well they would work on real-world social networks with different structural properties, or whether there exist other (potentially efficient) ways of Sybil defence. In this paper, we present a technique through which Sybil attack can be removed effectively as compared to existing techniques. By this method, there is reduced packet loss, throughput, jitter compared to the existing or classical approach of Sybil attacks. We show through simulation that Sybil attack can be prevented by proposed solution. Finally, we identify areas where further research could focus
