Overview of Routing Protocols in VANET

Abstract

Vehicular Ad-hoc Network (VANET) is an upcoming and emerging technology for intelligent transport technology (ITS) that enables Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communication by using various IEEE standards such as IEEE 802.11p. The high mobility of nodes in VANETs creates major challenges in routing the information packets to desired destination node which need to be addressed by differently devised routing protocols. Taking this into consideration, the paper gives an overview and tabular comparison of VANET and its various routing protocols with the prime focus given to protocols of V2V communication.
