Vehicular Ad-hoc Network (VANET) is a collection of communication vehicles, moving in different directions. The vehicles form a communication group to disseminate desired information. Various routing protocols are implemented in a VANET, each having benefits and shortcoming in the domain of implementation. In this paper performance of three routing protocols, namely Ad hoc On-Demand Distance Vector Routing (AODV), Destination Sequenced Distance Vector (DSDV) and Dynamic Source Routing (DSR) is compared for different parameters. The protocols are simulated on Network Simulator-2(ns- 2).
