Each node can acts as a router and forwards data packets to every other nodes in the network. Topology of the network changes very frequently due to mobility of the nodes. AODV(Ad-hoc on demand distance vector routing protocol) has been extensively used protocol in MANET. But AODV and other on demand routing protocol use single route reply. An extension version of AODV called RAODV (Reverse AODV) [11] tries multiple route replies and enhances the network performances like packet delivery ratio. Another extended version of AODV namely MAODV allows each node in the network to send out multicast data packets rather than sending unicast traffic. An evaluation of these two protocols has been carried out by using NS- 2.34.The comparisons of these protocols has been studied using some performance metrics like end to end delay, overhead by varying number of nodes which has not been done.

INTRODUCTION Mobile ad hoc network (MANET) plays an important role in the communication networks now-a- days and for coming advancement. The important role is the fact that as the distances among the nodes in an ad hoc network become very less, the network easily access information from space that provides capacity per Joule of energy. Recent research advances in low power, low cost and low rate wireless communications endure a promising future for the deployment of sensor networks to support a broad range of applications like health monitoring, habitat monitoring, target tracking and disaster management [1, 2, 3]. Mobile ad hoc networks consist of nodes that can communicate through the use of wireless links and do not form any static topologies. The fundamental features of these networks is that it does not possess any infrastructure and dedicated nodes which are present in the fixed kind of networks and provide network connectivity operations. For maintaining connectivity in a mobile ad hoc network all mobile nodes in the network go through routing operation of network traffic.
