Signal and Time Based Fuzzy Cluster Scheme to Detect Sybil Attack in VANET

Security is an important issue in the VANET environment and the Sybil attack affects it the most. In Sybil attack a node illegally claims itself as a legitimate node using multiple identities. This paper systematically analyses about Sybil attack and its effect in the VANET. We establish a Signal and Time clustering (STC) algorithm to detect the Sybil attack in VANET. The scheme provides a low complexity and low overhead solution which can be more efficient in a VANET environment.
