Abstract: This paper proposes a new congestion control algorithm for wireless sensor networks that it can assign a fair and effective transmission rate for each node. It designs the algorithm and describes the requirement of parameters(input and output speed, control efficiency, fairness, time interval, reverse data transmission) in algorithm. It also research the fluctuation of speed rate. Simulation results by using an event-driven packet level simulator show that the proposed algorithm can effectively improve the network throughput, ensure network fairness and reduce the energy consumption.
