Abstract: A dynamic routing management algorithm based on AODV protocol was proposed, to which the required different protocol parameters could dynamically be allocated so as to adapt it to the changing network contexts and improve its routing performance. Taking advantage of fuzzy logic, the MANET network contexts were classified in the algorithm and the different AODV routing parameters to be selected according to different network contexts for improving the routing performance. The algorithm was applied to AODV protocol and simulated by NS2 to compare its performance with standard AODV protocol. The simulation results showed that the algorithm can improve significantly the routing performance and that the application of fuzzy logic is available to optimizing the routing performance of MANET.
