ABSTRACT

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
