Vehicular Ad-Hoc Networks (VANETs), an emerging profile for the improvement of road safety that has a unique ability to possess inter-vehicle as well as vehicle-to-Road Side Unit communication that is to be implemented all across the globe in coming years. Since the communication is carried out along an open wireless medium which makes the network more vulnerable to attacks. Vulnerability of the network can either be the transmission of false information or vehicles assigned with fake identity, and they can possess identity of authorized vehicles or can even attack anonymously. Several techniques have been developed till date for the detection of unauthorized or illegitimate vehicles that downgrades the security of the network. This paper summarizes different techniques that have been developed for the detection of Sybil attack in VANETS.
