Fuzzy Control Routing Protocol for MANET Networks

?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 link. 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.
