摘要：An ad hoc wireless network is an autonomous self organizing system of mobile nodes connected by wireless links where nodes not in direct range communicate via intermediate nodes. The nodes use the services of other nodes in the network to transmit packets to destinations that are out of their range. Self configurability and easy deployment feature of the resulted in numerous applications in this modern era. Also, in case of disaster or natural calamities, the deployment of a fixed infrastructure is neither feasible nor economically profitable for establishing communication among the rescue members. In order to accomplish, a number of ad-hoc routing protocols have been proposed and implemented, which include dynamic source routing (DSR), Ad-hoc on Demand (AODV) and Destination Sequenced Distance Vector (DSDV) routing protocols. In this paper for experimental behaviour evaluation purposes, we have considered 500m x 500m, terrain area which illustrates the performance in terms of the packet delivery fraction and average end-to-end delay for DSR, AODV and DSDV routing protocols by using performance metrics, by changing the data transmission rate and basic transmission rate. Our results using NS-2 simulator shows that DSR performs better in both the case of packet delivery fraction and average end-to-end delay over DSDV and AODV routing protocolt strat
