Abstract: Mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Each node operates as an end system and also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change position frequently. They can be studied formally as graphs in which the set of edges varies in time. The main method for evaluating the performance of MANETs is simulation. In this paper work an attempt has been made to compare the performance of three on-demand routing protocols for MANETs:- Ad hoc On Demand Distance Vector (AODV), Dynamic Source Routing (DSR) protocols, and Temporally Ordered Routing Algorithm (TORA) with respect to the three performance metrics: average End-to-End delay, throughput and packet delivery ratio. The performance differentials are analyzed using varying number of nodes. These simulations are carried out using the ns-2 network simulator. The results presented in this work illustrate the importance in carefully evaluating and implementing routing protocols in an adhoc environment.
