摘　　要：针对无线传感器网络中由于拥塞引起的丢包和能量过度消耗等问题,提出了一种基于蚁群优化的拥塞控制算法以减轻WSN中的拥塞和改进网络性能。该算法充分考虑了给定时刻WSN的拥塞状况,分成三个阶段在源节点和sink节点间寻找一条最佳的路径,并及时地消除拥塞。仿真实验结果表明,该算法在网络吞吐量、丢包率、时延和能耗方面具有较好的综合网络性能。In view of packet loss and excessive energy consumption due to congestion in wireless sensor networks,this paper proposed a congestion control algorithm based on ant colony optimization to reduce congestion scale and improve network performance in WSN.The algorithm was divided into three stages in the given time,and fully considering the congestion status of WSN from source node to sink.The algorithm could timely eliminate congestion and find a best path.Simulation results show that the algorithm can achieve good network performance about network throughput,packet loss,delay and energy consumption.
