An Efficient Fuzzy Based Congestion Control Technique for Wireless Sensor Networks

In Wireless Sensor Networks (WSN), congestion causes overall channel quality to degrade and loss rates to increase, leads to buffer drops and increased delays, and tends to be grossly unfair toward nodes whose data has to traverse a larger number of radio hops. In order to control the congestion in an effective manner, the authors need a complete congestion control mechanism which makes fuzzy based decisions. In this paper, they design an efficient fuzzy based congestion control algorithm which takes into consideration the node degree, queue length and the data arrival rate as parameters for congestion detection.
