Fuzzy Controller Based Stable Routes with Lifetime Prediction in MANETs

In ad hoc networks, the nodes are dynamically and arbitrary located in a manner that theinterconnections between nodes are changing frequently. Thus, designing an effective routingprotocol is a critical issue. In this paper, we propose a fuzzy based routing method thatselects the most stable route (FSRS) considering the number of intermediate nodes, packetqueue occupancy, and internodes distances. Also it takes the produced cost of the selectedroute as an input to another fuzzy controller predicts its lifetime (FRLP), the evaluation of theproposed method is performed using OMNet++4.0 simulator in terms of packet delivery ratio,average end-to-end delay and normalized routing load.
