摘要：In wireless networks, due to huge amount of packets convergent nature of upstream traffic and limited wireless bandwidth, network congestion happens easy, which is a serious problem to be solved. The congestion control scheme is necessary to be solved out which can detect congestion precisely and regulate it fairly. To achieve this objective, a fuzzy logic based congestion control is proposed which takes advantage of current buffer occupancy and congestion detection is proposed to diagnose problem at each node level. In addition, it periodically calculates the congestion degree using fuzzy logic theory. At the same time each upstream traffic rate is emphasized according to the value of congestion degree. The scheme can quickly solve the status and trends of the network load, and adjust quickly to avoid a lot of packet losses. Simulations are conducted for the proposal which shows that this implementation efficiently sorts out the traffic and minimizes the packet loss. Simulation model also addresses the problem in order to deprive the congestion in wireless network
