Overview of Various Attacks in VANET

VANET stands for Vehicular Ad-hoc Network. It is the sub category of MANET(Mobile Ad-hoc Network). It serves a critical infrastructure for road safety and traffic efficiency. It is an emerging technology to achieve intelligent inter vehicle communication that results in improved road safety and essential alerts.(1) Vehicular Ad hoc Network (VANET) serves user with safety and non safety applications but needs security to implement the wireless environment In VANET vehicles does not have fixed infrastructure because of the reasons that vehicles are nodes with mobility. It serves safe and non safe wireless applications due to which security is most important concern in VANET. In this paper we will present comprehensive study of various attacks in VANET and comparison of various attacks in VANET. "(1),(3)"
