A Review of Various Routing Protocols in VANET

Abstract

Vehicular Ad Hoc Networks (VANET) is a subclass of Mobile ad hoc networks which provides a distinguished approach for Intelligent Transport System (ITS). VANET's provide communication between vehicles moving on the roads.Many protocols have been adopted to serve different topology and scenarios. We introduce and reviewPosition based Routing Protocols, Broadcast based routing protocols, Multicast/Geocast routing protocols, Cluster based routing protocols. The survey of routing protocols in VANET is very essential and necessary for smart ITS. This paper also discusses the advantages / disadvantages and the applications of the above mentioned routing protocols for vehicular ad hoc networks. The challenges and perspectives of routing protocols for VANET's are finally discussed.
