PERFORMANCE METRIC COMPARISON OF AODV AND DSDV ROUTING PROTOCOLS IN MANETs USING NS-2

Efficient routing protocols can provide significant benefits to mobile ad hoc networks in terms of both performance and reliability. Mobile Ad-hoc Network (MANET) is an infrastructure less and decentralized network which need a robust dynamic routing protocol. Many routing protocols for such networks have been proposed so far. Amongst the most popular ones are Dynamic Source Routing (DSR), Ad-hoc On-demand Distance Vector (AODV), Temporally Ordered Routing Algorithm (TORA) and Destination-Sequenced Distance Vector (DSDV) routing protocol. The performance of AODV and DSDV routing protocol have been evaluated for Mobile Ad-hoc Networks (MANETs) in terms of throughput, the average end to end delay, jitter and drop etc. The performance of the AODV is better than the performance of the DSDV routing protocol. A network simulator-2 (NS-2) called MobiREAL simulator has been designed and developed for performance evaluation of AODV and DSDV routing protocol in this paper. To compare the performance of AODV and DSDV routing protocol, the simulation results were analyzed by graphical manner and trace file based on Quality of Service (QoS) metrics: such as throughput, drop, delay and jitter. Finally, the performance differentials based on network load, mobility, and network size have been analyzed. The simulation result analysis verifies the DSDV and AODV routing protocol performances.
