摘　　要：分析了矿井的路由需求,选择了基于位置信息可知的GEAR协议作为研究对象,对GEAR协议进行了改进,引入极坐标系从而提出了一种带移动节点的网络模型,使其更符合煤矿井下的要求。经过NS2的仿真,改进后的GEAR协议使得整个网络在较低的能耗水平下获得了较长的生命周期,具有较好的能量优化特性。This article analyzed the needs of routing, choosed GEAR protocol as the research object, this paper improved the GEAR protocol according to actual demand, and put forward a network model with mobile nodes by introducing polar coordinate system, established two simulation environment, and It will improve the security of communication. The result demonstrates that the improved GEAR routing protocol enables the whole network has long lifetime on the low power level and has comparatively good power optimum property by simulation on NS2 platform.
