Evaluating the Impact of Different Routing Protocols on VANET Performance

Vehicular Ad Hoc Networks (VANETs) are the backbone of Intelligent Transportation Systems, aiming to enhance road safety, traffic efficiency, and comfort in driving. One of the critical factors influencing VANET performance is the routing protocol implemented. The current study evaluates the impact of three different routing protocols, i.e., Ad-hoc On-demand Distance Vector (AODV), Destination-Sequenced Distance Vector (DSDV), and Dynamic MANET On-demand (DYMO) on VANET performance in urban scenarios. Through comprehensive simulations using a realistic city scenario, we assess each protocol's performance based on several critical metrics such as packet delivery ratio, end-to-end delay, and network overhead. Our findings indicate significant differences in the performance of these protocols under various urban network conditions (AODV), being the best among all.
