چکیده
ABSTACT Vehicular Ad-Hoc network is a type of Mobile ad-hoc Networks, vanet help in developing communication between near vehicles and between vehicles and roadside equipment. The paper aims to investigate the performance of the routing protocol in vanet by using tcp variants that is tcp reno, tcp new reno and tcp tahoe.In the performance evaluation two different routing protocols On-Demand Distance Vector (AODV) and Optimized Link State Routing (OLSR) have been considered with three different TCP variants. Delay and Throughput are the two parameters that are consider to grade the routing protocol.. Conclusions are drawn based on the evaluation results using OMNET++ and SUMO simulator. The results clearly show that the both AODV and OLSR achieve acceptable performance. However, the merits of AODV over OLSR or vice versa depend on the network environment such as TCP variant used, traffic load, number of nodes with the required parameter in the evaluation delay or the throughput. The results clearly show that selecting best protocol is depend upon network condition because olsr protocol achieve better performance compare to aodv protocol from the throughput point of view and matter is different in case of delay.
