Fast route recovery scheme for Mobile Ad Hoc Networks

A Mobile Ad Hoc Network (MANET) is a self-configuring network of mobile devices connected by a wireless link. 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. AODV-BR and AODV-ABR schemes improve the AODV routing protocol by supplying multiple backup routes, but may be inefficient in a dense environment. In this paper, we propose a novel fast route recovery scheme which employs local recovery of routes for reliability and reduces the number of control messages for efficiency of the network. Our scheme considers a backup node´s mobility and conducts a route recovery process implicitly. Simulation results show that our scheme improves the routing protocols.
