SIMULATION BASED AND ANALYSIS OF ROUTING PROTOCOLS FOR VANET USING VANETMOBISIM AND NS-2

Vehicular Ad hoc Network (VANET) is a distributed, self-organizing communication networks built up by vehicles traveling on the streets; with expected to benefit in safety applications, and disseminating real-time traffic congestion. VANET is thus characterized by very high speeds and limited degrees of freedom in nodes movement patterns, such particular features often make standard networking protocols inefficient and effect on performance of routing protocols. Therefore, routing protocols in VANET is become a challenging task. This research paper analyzes routing protocol based on the performance metrics like packet delivery ratio, average end-to-end delay and throughput of the network under VANET environments using a network simulator (Ns-2) for simulating network connection and VanetMobiSim for generating the mobility pattern of vehicles. This experiment has provided insight into the performance of routing protocols for urban random scenario. Finding indicates simulation of different number of nodes only marginally affected VANET routing performance in our experimental settings.
