Abstract: A mobile ad-hoc wireless network's character was introduced. Based on the dynamic source routing (DSR) protocol, an efficient on-demand routing protocol is presented, called the extension of the dynamic source routing (EDSR) protocol. The use of fuzzy controlling techniques was investigated. For each metric, a fuzzy membership function was defined to predict a more stable Sink. A fuzzy-inference rule base was implemented to generate the fuzzy cost of each link. The protocol selects the most stable path based on mobility prediction and establishes multiple paths for a route discovery procedure, thus conserving network bandwidth and reducing route reconstruction times when routes path failed. Compared with DSR, the protocol has high packet delivery ratio with low control overhead.
