A Survey based on Routing Mechanism in Transport Entities for Vehicular Networks

In today’s time vehicle to vehicle (V2V) communication attracted the researchers as an attractive research area of intelligent transport control systems. Network formed due to V2V communication forms vehicular ad hoc networks called VANET. The basic concept in such communication is to encourage the safety messages for one to many vehicles via a wireless medium. Since transport entities like car, bike, truck, ambulance etc. need to exchange messages via creating a temporary network using multiple hops. This makes difficulty to select efficient routing mechanism due to high mobility of vehicles. The delivery of safety messages in such network is challenging task since it needs to handle rapidly changing network topology. So in this paper, a survey of various routing mechanism developed in transport entities for Vehicular network is presented and concluded with each routing mechanism advantages and limitations.
