Performance Evaluation of On-demand AODV and DSR Routing Protocols in Mobile Ad-hoc Network

Wireless networks history began in the period of 1970s and the awareness has been increasing ever since. Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes, which build network dynamically, and does not require any infrastructure support for transferring data packet between two mobile nodes. These are often known as infrastructure-less networking because the mobile nodes in such network establish routes between themselves dynamically. Communication and administrative tasks can be carried out between the computers without using any wire. MANETs are recognized by infrastructureless environment, multihop wireless connectivity, and frequently changing topology. An experimental analysis regarding performance evaluation of well known ad hoc protocols AODV and DSR has been carried out using network simulators OPNET 14.0. To evaluate the performance of AODV and DSR random mobility model is used and performance differential parameters are analyzed in terms of throughput, end to end delay, network load and packets dropped with varying node speed, network density and pause time.
