A Fuzzy-Based Routing Strategy to Improve Route Stability in MANET Based on AODV

In recent years, mobile ad hoc network (MANET) is becoming more and more useful in many domains. While MANETs still suffer from several problems. Among these problems, the energy conservation. Where the energy presents one of the greatest restriction, and has a massive effect on others metrics like packet delivery ratio, overhead, end-to-end delay and the lifetime of the network. As most of mobile ad hoc stations based on a limited battery in their mission. For these reasons, we propose in this paper a fuzzy logic system (FLS) to enhance the performance of one of the reactive routing protocols Ad hoc On-demand Distance Vector (AODV) by avoiding nodes with low amount of energy and select the more stable path. Our fuzzy system uses three input parameters that have a large impact on the stability of the links: energy drain rate, mobility of the node and the distance between two communicating nodes. Simulation results show that our protocol gives good result by reducing significantly the energy dissipation, also certain parameters affected by the energy issue.
