An Entropy-Based Fuzzy Controllers QoS Routing Algorithm in MANET

In mobile ad hoc networks (MANETs), the provision of quality of service (QoS) guarantees is much more challenging than in wireline networks, mainly due to node mobility, multihop communications, contention for channel access, and a lack of central coordination. This paper introduces an Entropy-based Fuzzy controllers QoS Routing algorithm in MANET (EFQRM). The key idea of EFQRM algorithm is to construct the new metric-entropy and fuzzy controllers with the help of entropy metric to reduce the number of route reconstruction so as to provide QoS guarantee in the ad hoc network. The simulation results show that the proposed approach and parameters provide an accurate and efficient method of estimating and evaluating the route stability in dynamic MANETs.
