Survey of Routing Protocols in Vehicular Ad Hoc Network

Vehicular Ad Hoc Network (VANET) is a subclass of Mobile Ad Hoc Networks (MANET) which provides a distinguished approach for Intelligent Transport System (ITS). Routing protocols in VANET are important and necessary issue for smart ITS. With the development of vehicles and mobile ad hoc network technology, the VANET has become an emerging field of study. It is a challenging problem for searching and maintaining an effective route for transporting data and information. Several protocols are there in Ad hoc networks that are used for sharing information, ensuring safety, informing climatic and weather conditions and giving necessary road and traffic positions for better and smooth movement of vehicles. This paper gives an overview of routing protocols in Vehicular Ad hoc network.
