Abstract: “A Wireless ad hoc network is a collection of autonomous mobile nodes that communicate with each other over wireless links without any fixed infrastructure. The nodes use the service of other nodes in the networkto transmit packets to destinations that are out of their range. A number of ad-hoc routing protocols have been proposed and implemented which include ad-hoc on demand Vector Protocol (AODV) , dynamic source routing (DSR) and Destination sequenced Distance Vector (DSDV) routing protocols. In this paper for experimental evaluation purposes, we have considered 600m x 600m, terrain area which illustrates the performance in terms of the packet delivery fraction, average end-to-end delay ,normalized routing load and throughput for routing protocols. Our simulation results using NS-2 shows that DSDV performs best in all the cases of packet delivery fraction, average end-to-end delay , normalized routing load and throughput over other routing protocols on varying mobility speed using G”
