Mobile Ad hoc NETwork (MANET) is an infrastructure less multi hop wireless network, were there is no any centralized access. MANET is a self-configuring and self-organizing collection of mobile nodes. As nodes have given mobility, it is very complex task to manage the routing. As in MANETs, every node can work as the host as well as the router such that can receive and send the packet. As in MANET the network topology is dynamic and frequently changes, so routing protocols should be designed to meet the requirement of the MANET.
