摘　　要：网络数据传输过程中传输节点耗能过大、传输数据量过多,导致信息传输不分主次造成网络拥堵,会造成地铁通信传输存在不同程度的延迟问题。针对这一问题,提出基于无线传感器网络的地铁通信传输延迟优化方法。采用受控自回归积分滑动平均模型预测分析通信状态,分辨出高质量信息并对其调度传输,同时通过传输数据模型选取节点最优的参数,控制传输节点能耗,配置网络并生成多个区群结构,结合传输节点能量消耗控制参数调节数据压缩率,实现传输延时优化。仿真结果表明,所提方法发送和接收延迟小,能够有效减少网络拥堵现象,且降低数据丢失问题,保持传输信息精准,适用性较强。In the process of network data transmission,the transmission nodes consume too much energy and transmit too much data,which leads to the network congestion and delay of metro communication.In order to solve this problem,an optimization method of metro communication delay based on wireless sensor network is proposed.The controlled autoregressive integral moving average model is used to predict and analyze the communication status,distinguish high-quality information and schedule transmission to it.At the same time,the optimal parameters of nodes are selected through the transmission data model to control the energy consumption of transmission nodes,configure the network and generate multiple area group structures,and adjust the data compression rate in combination with the control parameters of energy consumption of transmission nodes to realize the optimization of transmission delay.Simulation results show that the proposed method can effectively reduce network congestion,reduce data loss,and maintain the accuracy of transmission information,and it has strong applicability.
