Analysis of Sybil Attack Isolation Technique in VANET

The vehicular ad hoc network is the decentralized type of network in which vehicle nodes can join or leave the network when they want. The vehicular network is much vulnerable to security attacks which affect network performance. The active attacks are those which reduce network performance in terms of certain parameters. This paper is related to Sybil attack. The techniques which are proposed for the isolation of Sybil attack is reviewed and analyzed in this paper. The techniques are implemented in the network simulators and results are analyzed in terms of certain parameters.
