Abstract

In the design of an intelligent transport system, Vehicular Ad Hoc Networks (VANETs) plays an important role, so it is considered an emerging research area. The major research area in VANET is routing. The most challenging thing is to find the appropriate routing protocols for a specified type of transmission and the continuously varying topologies, and which routing performances are more stable and consistent. A comparative study and analysis of the reactive routing protocols, Dynamic Source Routing (DSR) and Ad-Hoc on Demand Distance Vector (AODV) is presented here. Based on more than one performance metric like the end to end delay, throughput, Packet Loss Ratio (PLR), Packet Delivery Ratio (PDR), and Overhead transmission (OH), the two reactive protocol’s are compared to choose the best route in a VANET. In different scenarios, one protocol performs out the other; DSR is in the upper hand from a consolidated evaluation. It is concluded that the most preferred protocol is DSR because DSR is more consistent and stable than AODV.
