Abstract-The route recovery algorithm is a crucial part of an ad hoc routing protocol. Designing an efficient and fast route recovery mechanism scheme without incurring extra overheads or delays to repair the broken link is a desirable goal for any routing protocol. The route recovery algorithm in reactive routing protocols like AODV occurs only after a link failure is detected. However, we propose a new route discovery mechanism called Route Migration over Multiple link failure in Multi-Channel (RMMMC), which combines multiple paths and channels to provide a disjointed alternative route. When link failure is detected, the RMMMC reroutes the data packet through the alternative route in alternative channels that have been previously discovered. Furthermore, the RMMMC is resilient to multiple link failures. Unlike other route recovery approaches, nodes in RMMMC are considered to be equipped with a single transceiver. The RMMMC scheme is implemented and extensively evaluated by using an ns-2 simulator. Simulation results show that the proposed scheme achieves a better packet delivery ratio, throughput and reduces the routing overhead and end-to-end delay in a dense network.
