In Mobile Ad-hoc NETwork (MANETs), several works exist for reliable local route recovery process. But most of the mechanisms perform route recovery reactively rather than predicting the route failures proactively. Moreover the route failure detection or prediction is not so accurate and the metrics used for failure estimation are also not unique. In this paper, the authors propose a fuzzy based route recovery technique. It consists of two phases, Proactive failure discovery and Route failure recovery. Nodes in the network estimate the metrics Link Expiration Time (LET), Received Signal Strength (RSS), Available Band Width (ABW) and Residual Energy (RE) and using fuzzy logic, the type of node is estimated as weak, normal or strong.
