传输调度是提高无线网络通信性能的重要手段，针对工业无线传感器网络，文章提出一种基于距离矩阵的动态调度方法。根据网络的拓扑结构建立初始时隙分配计划以及距离矩阵，构建时隙分配表并确定节点的发送和接收时隙。该方法既考虑了网络拓扑结构的影响，又考虑了节点数据产生周期的影响。仿真结果表明，该方法能显著降低网络的平均发送时间，提高数据传输的保真度。%Transmission scheduling is an important approach to improve wireless network performance . In this paper ,a distance matrix based dynamic scheduling method for Industrial Wireless Sensor Net-works(IWSNs) is presented .In the method ,the initial slot allocation plan and the distance matrix are constructed according to the network topology ,the slot allocation table is established ,and then the transmitting and receiving slots of nodes are determined .The method not only takes into account the impact of network topology ,but also considers the impact of data generation cycle of nodes .The simu-lation results show that the method can dramatically decrease the average response time of the net-work and improve data fidelity .
