Abstract
VANET represent a rapidly emerging and challenging class of MANET. In this type of network,
each node operates not only as a host but also as a router; promote packets for other mobile nodes.
Communication between nodes i.e. vehicles by means of wireless technology has a large potential
to improve traffic safety and travel comfort for drivers and passengers. VANET, being an
infrastructure-less networks, vehicle will be expected to cooperate to perform essential
networking tasks such as routing.In this work, nodes have been used as vehicles and based on
evaluation between four mostly used routing protocols Ad hoc on demand distance Vector routing
protocol (AODV), Dynamic source routing protocol (DSR), Optimized link state routing (OLSR)
and Geographic Routing Protocol (GRP) in VANET scenario. 30 sec time is taken for simulation
with varying nodes i.e. 5 nodes, 20 nodes and 40 nodes. Various mobility have been analyzed
here which are 10 m/sec and 28 m/sec and performance has be
