Safe Traffic Adaptation Model in Wireless Mesh Networks

Abstract

Wireless mesh networks (WMNs) are dynamically self-organized and self-configured technology ensuring efficient connection to Internet. Such networks suffer from many issues, like lack of performance efficiency when huge amount of traffic are injected inside the networks. To deal with such issues, we propose in this paper an adapted fuzzy framework; by monitoring the rate of change in queue length in addition to the current length of the queue, we are able to provide a measure of future queue state. Furthermore, by using explicit rate messages we can make node sources more responsive to unexpected changes in the network traffic load. The simulation results show the efficiency of the proposed model.
