Vehicular Ad-hoc Network, its Security and Issues: A Review

Vehicular ad hoc network (VANET) is a vehicle to vehicle (VVC) and roadside to vehicle (RVC) communication system. The technology in VANET incorporates WLAN and Ad Hoc networks to achieve the regular connectivity. The ad hoc network is brought forth with the objectives of providing safety and comfort related services to vehicle owners. Collision warning, traffic congestion warning, lane-change warning, road blockade alarm (due to construction works etc.) are among the major safety related services addressed by VANET. In the other category of comfort related services, vehicle users are equipped with Internet and Multimedia connectivity. The major research challenges in the area lies in design of routing protocol, data sharing, security and privacy, network formation etc. We aim here to study the overview of VANET and its security issues
