A Comparative Study Of Various Routing Protocol For VANETs

Abstract

Vehicular Ad hoc Network (VANET) is most active

research area that provides wireless communication between

vehicles moving at high speeds. These networks are self

organized in nature and a key component for future intelligent

transportation system (ITS). It is a subclass of mobile ad hoc

networks (MANET) but with some different characteristics like

high mobility of vehicles, constrained mobility, highly dynamic

topologies, frequent disconnections of networks, bandwidth

limitation, no power constraints, sufficient storage and

unpredictable node density. It is difficult to develop an efficient

routing protocol for VANETs. In this research paper, we have

discussed some existing ad hoc routing protocols AODV, DYMO

and OLSR. Also, we have presented the comparative study of

these routing protocols along with their advantages and

disadvantages
