A Fuzzy Logic-Based Distance Broadcasting Scheme For Mobile Ad Hoc Networks

An on-demand route discovery method in Mobile Ad hoc NETworks (MANET) uses simple flooding method, whereas a mobile node blindly rebroadcasts received Route REQuest (RREQ) packets until a route to a particular destination is established. Thus, this leads to broadcast storm problem. This paper presents a novel algorithm for broadcasting scheme in wireless ad hoc networks using a fuzzy logic system at each node to determine its capability to broadcast route request packets, based on the node location. The authors' simulation analysis shows a significant improvement in performance in terms of routing overhead, MAC collisions and end-to-end delay while still achieving a good throughput compared to the traditional AODV.
