Abstract: In MANET routes between nodes changes regularly due mobile nature of all network nodes. It is always challenging task to discover an optimal path. Due to change in network topology some parameters are also effected like network delay, packet drop and throughput etc. There are basically three categories of protocols are reactive, proactive and hybrid. But reactive protocols have wide popularity in this field and provide solution to overcome problems (change in parameters) related to adhoc network. This paper evaluates behaviour of reactive protocols (AODV, DSR) using remote login type traffic in MANET. In this paper some parameters like network delay, total packet drop, network load and throughput are calculated with help of OPNET Modeller 14.5.

Keywords: OPNET, MANET, AODV, DSR and Remote login
