摘要: 为给无线传感器网络中每个节点分配一个公平有效的传输速率,提出一种新的拥塞控制算法。分析算法对平均输入输出速率、控制效率、公平性、时间间隔、逆向数据传输等参数的要求,研究速率抖动对算法的影响,并在事件驱动的数据包级模拟器上验证该算法。实验结果表明,该算法能有效提高网络吞吐量,保证网络公平性,降低能耗。

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.

Key words: Wireless Sensor Network(WSN), congestion control algorithm, throughput, fairness, energy consumption
