Abstract: Mobile Ad hoc Network (MANET) is an autonomous system of mobile hosts connected by wireless links. MANET can be formed without any preexisting infrastructure. It follows dynamic topology where nodes may join and leave the network at any time and the multi-hop routing may keep changing as nodes join and depart from the network. This paper proposes a fuzzy based routing protocol for MANETS that considers the following parameters as inputs: Hop count and Total Transmission power, data size and highest node speed. On the basis of the outputs of Fuzzy modules an optimal path is proposed. The proposed protocol is implemented in MATLAB-7.0 and our result also shows that our proposed protocol is better than other standard protocols such as shortest path routing and MTPR (Minimum transmission power routings).
