Since few years, vehicular ad hoc networks deserve much attention mainly security and privacy have the most important concerns. In VANET, many attacks rely on having the attacker generate multiple identities to simulate multiple nodes: this is called the Sybil attack. In this paper, the authors propose a new mechanism to detect Sybil attacks. In proposed system, one mobile node is treated as base station and remaining nodes send their ID and power value to base station. Base station detect the Sybil nodes based on its power value i.e., if power value is less than minimum value.
