A Fuzzy Based Congestion Control in Distributed Wireless Network

In Distributed wireless network, this paper propose the traffic management for controlling the congestion, in which routers are associated with intelligent controllers to manage buffers and transfer packets for wired/wireless networks. By analyzing various existing traffic control protocols, which estimates auxiliary network parameters such as link latency, bottleneck, bandwidth, packet loss rate and the number of flows for evaluating the performance of the network. The fuzzy logic based controller can measure the router queue size directly by using congestion control algorithm. The performance is measured in terms of the packet loss percentages, link utilization and queue size. The Quality of service is assured by the good performance of the fuzzy based controller using Target buffer Occupancy in network dynamics. In this new methodology, the classical and fuzzy logic have been combined by a blending mechanism which provides better performance than various explicit traffic controllers using the network simulator. Key terms: Distributed wireless network, fuzzy logic, source sending rate, , congestion control.
