Abstract Mobile Ad hoc networks (MANETs) are a set of wireless mobile nodes which dynamically connect and transfer information. The open and dynamic operational environment of MANETs makes it vulnerable to various attacks. In this paper, an attempt has been made to investigate the impact of selfish node on the performance of AODV routing protocol by varying simulation time through OPNET Modeler version 17.5. Experimental results reveal that by varying simulation time, the performance of routing protocol without selfish node also varies, to obtain the steady state behaviour of a routing protocol the selection of simulation time plays a vital role. The minimum value to obtain the steady state behaviour through results is observed as 1500 sec. The impact of selfish node on performance of the throughput degrades by 40 times of the original AODV throughput. Similarly, the delay is reduced by more than 1000 times. The impact of the simulation time on the performance of the variance in throughput of AODV routing protocol with and without the selfish node is 2532 and 98 and delay in variance is 0.00012 and 0.00000376 sec.
