Efficiency Evaluation of DSR and AODV On-demand protocols in Wireless MANETs

Abstract

Mobile Ad hoc Networks (MANETs) are becoming indispensable and ubiquitous in future due to proliferation of laptops and mobile phones. These short lived networks are an effective solution in emergency conditions. These networks can be created anytime, everywhere by portable wireless devices such as smart phones and laptops without any installation and infrastructure cost. Distant mobile nodes communicate with each other with cooperation of other nodes which relays communication packets by acting as routers. Due to freely movement of mobile nodes independently in any direction, routing is a challenging issue in ad-hoc network. Different routing protocols have been introduced for discovering and maintaining a route in ad hoc network. These routing protocols are of three categories viz. table driven, reactive and hybrid protocols. In our paper, we have used AODV and DSR routing protocol to find efficient and shortest route in MANET. Our simulation results demonstrate that AODV routing protocol outperforms DSR routing protocol in terms of packet delivery ratio and throughput.
