Vehicular Adhoc Network – A Review

Vehicular ad hoc network (VANET) is a most important type of network, which has characteristics to provide vehicle-to-vehicle (V2V) and vehicle to infrastructure(V2I) communication on the road. It is an approach for intelligent transportation system. VANET Works like as mobile ad hoc network. It provides many applications like as message transmission from one vehicle to another, data transmission, map guidance, entertainment and so on. VANET helps to reduce the causes of accidents on a highway. Vehicles can convey messages related to status of the road and other informational messages to each other. Throughout this paper, we will discuss simulation tools, architecture, applications, security concern and routing approaches used for message communication among vehicles. We provide a research review on vehicular ad hoc network.
