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.

关 键 词:无线传感器网络  矿井  GEAR协议

Abstract:This article analyzed the needs of routing, choosod 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 sys-tem, established two simulation environment, and It will improve the security of communication. The result demonstrates that the im-proved 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.
Keywords:wireless sensor network  coal mine  GEAR protocol
