COMPARATIVE PERFORMANCE EVALUATION OF AODV AND AOMDV IN VEHICULAR ADHOC NETWORK

Vehicular Ad hoc Network (VANET) is a new way of communication which includes communication between vehicles moving at high speeds on the roads.VANET is subset of MANET.Vehicular Area Networkproviding emergency services and other information in both urban and rural setup.Vehicles can communicate with each through protocol.Protocols in VANET can classified as Topology Based ,Position Based , Geocast Based , Cluster Based ,Broadcast based , Infrastructure based . Reactive protocols Determine a route only when there is data to send.Each node forwards the request only once.Each node maintains a routing table that contains information about reaching destination nodes. In this paper Topology based reactive protocols AODV and AOMDV are presented.
