Evaluation of routing protocols in congested VANET environment

Vehicular Ad-Hoc Network (VANET) is an exponential growing technology in today's modern computing era. Vehicle are peers of peer to peer network. All vehicles are having mobility. In this paper we have presented an evaluation of routing protocols AODV, DSDV and DSR on basis of test performance metrics like generated packets, received packets, dropped packets, average end to end delay, average throughput, and packet delivery ratio. We have setup an experimental topology of VANET with vehicles deployed on Random-way-point mobility model and having a limited speed to simulate the congested roads and traffics. Ours simulation has shown that DSDV exhibits higher packet delivery ratio than other two protocols, has moderate average end to end delay and highest throughput.
