A Mobile Ad-hoc NETwork (MANET) is a self configuring Network of mobile devices connected by a wireless link without fixed infrastructure. In MANETs, the data packet may fail to be delivered for various reasons including nodes movement, packet collision and bad channel condition. Because re-route recovery of traditional on-demand routing protocols has high latency, several ideas have been proposed to solve this problems. By improving the AODV routing protocol and by supplying multiple backup routes, but may be inefficient in a dense environment. To overcome this problem RR-AODV (Route Recovery) scheme was introduced. This employs local recovery of routes for reliability and reduces the number of control messages with the help of backup nodes to improve the efficiency of the network.
