Abstract: A Mobile Ad-hoc Network MANET is a dynamic wireless network that is formed even if an infrastructure in which each nodes act as a router does not exist. MANET is an autonomous system in which mobile nodes are connected by wireless links. All the nodes operate as an end system and as a router, to route packets. The nodes are freely movable and organize themselves into a network. The change in positions of these nodes is frequent. In this work we attempt to compare the performance of three prominent on demand reactive routing protocols AODV, DSR and AOMDV.
