Abstract :

A Mobile Ad Hoc Network (MANET) is a self configuring Network of mobile devices connected by a wireless link without fixed infrastructure. In MANETs, data packets fail to deliver to destination node due to packet collision, nodes movement and bad channel condition. When packets fail to be delivered, source node must perform re-route discovery process. In traditional on demand routing protocols, re-route discovery involves high latency and large control message overhead. Hence it reduces the network efficiency. In this paper, reliable route recovery scheme takes advantage of backup route. This scheme provides local recovery of routes for reliability and reduces the number of control messages for network efficiency. RRR-AODV scheme establishes multiple backup nodes for route recovery process implicitly. The backup nodes make routing table and stores data in buffer. If there is any link failure then the backup node sends route change packet to the node which tries for re transmission. This scheme not only reduces message overhead but also improves the routing performance.
