SEGREATION OF SYBIL ATTACK USING NEIGHBOURING INFORMATION IN VANET

Abstract: Sybil attack bogus traffic scenario by sending fake message with multiple ID which often cause jam and accident in VANET. It is very hard to defend and establish when it is eject by devise attackers using their real ID. In this paper, we present Neighbor based information (NBH) in which trust value is to be calculated by their neighbor node which restrain to spread false message. NBH can detect Sybil attack with stolen ID. Simulation results show that proposed technique increases the detection and reduces the percentage of Sybil attack.
