Abstract
A Mobile Ad-hoc Network is a collection of mobile nodes that form a wireless network and the mobile
nodes dynamically communicate to other nodes without the use of any preplanned infrastructure. 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 NS2.34.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.
