摘　　要：分析了煤矿井下人员定位无线传感器网络固定节点特定拓扑结构,提出了一种基于路由表的地理位置路由算法GRBT。该算法采用一种基于网络梯度和位置信息的策略构建路由表,既简化了数据传输过程,又建立了最优数据传输路径。仿真结果表明,该算法下的网络具有较低的数据传输延迟和较好的鲁棒性和可扩展性,能够满足煤矿井下人员定位无线传感器网络实时传输信息的应用需求。Analyzes the fixed node specific topology structure of wireless sensor network for personnel positioning in mine, and puts forward a geographic routing algorithm based on routing table. The algorithm adopts a strategy based on the network gradient and location information to construct routing tables, which simplifies the process of data transmission and establishes the optimal data transmission path. Simulation results show that the network has low data transmission delay, good robustness and expansibility. It is suitable to be applied to the real-time transmission information of wireless sensor network for personnel positioning in coal mine.
