Performance Evaluation of AODV, DSDV and DSR Routing Protocols using NS-2 Simulator

MANET stands for Mobile Ad-hoc network, in which mobile nodes are connected with each other through wireless connection. In this paper we are analyzing the performance of three routing protocols AODV DSR (Dynamic Source Routing) and DSDV (Destination-Sequenced Distance Vector routing). Comparison of these wireless multi-hop routing protocols, which will be based on the performance metrics, Packet Delivery Ratio (PDR), End to End delay and Throughput, with varying the number of nodes and speed. Simulation of these protocols provides the results which shows better performance of a protocol under a particular situation. The simulation is carried out using Network Simulator, due to its open source simplicity and free availability.
