摘　　要：与传统的无线网络相比,大时滞网络对路径拥塞环境下的无线通道交换具有较高的要求。为此提出主动队列管理下大时滞网络路径拥塞控制算法。首先利用主动队列管理算法对相邻路由节点网络路径的拥塞情况展开预测,进而分析网络路由节点的队列状态;然后以优化后续节点队列、传输距离以及传输方向为目的,从路径概率选择、分组丢弃函数、WSN蚁群路由选取三个角度优化网络路径,从而实现路径拥塞控制。实验结果表明,上述算法能够有效缩短网络的传输时滞,且能耗和丢包率较低,具有较高的应用价值。In the large time-delay network,there is a high demand for wireless channel switching in path congestion environment.In this regard,this paper puts forward a path congestion control algorithm with active queue management for large delay networks.Firstly,based on the active queue management algorithm,the congestion of the network path of the adjacent routing nodes was predicted,and the queue status of the network routing nodes was analyzed.Secondly,the optimization of subsequent node queue,transmission distance and transmission direction were taken as indicators to optimize the network path from path probability selection,packet drop function and WSN ant colony routing selection.Eventually,path congestion control was completed.The simulation results show that the algorithm has short transmission delay,low energy consumption and packet loss rate,and high practicability.
