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.
