Abstract
In Vehicular ad-hoc networks (VANET) there is need to tackle various security concerns before they employed. VANET provides safe journey with the help of various secure services and applications thereby plays a critical role in creating Intelligent Transportation system (ITS). Security and privacy problems should be considered prior to their placement to make sure that the secure communication in VANET but along with secure & efficient authentication, Privacy preservation should be also considered to tackle with various complicated communication scenarios [1]. An extensive survey on various privacy preserving in VANET schemes like 2-Flip, EAAP, NECPPA, VSPN, SPACF & PSPPS is done in this paper and an efficient privacy preserving scheme is withdrawn from it on the basis of communication overhead, Message delay & various performance metrics. Extensive review shows that the 2-Flip Privacy Preservation scheme satisfy almost every performance metrics and have least message delay & commination overhead.
