摘要 针对用于井下矿压监测系统的无线传感器网络节点呈带状静态分布的特点,以最小跳数路由协议为研究对象,对其路由创建阶段、数据传输阶段、维护更新阶段进行改进,提出了一种节点能量分级的最小跳数路由协议。该路由协议通过对节点能量分级处理的方式,减少了控制分组和数据传输路径的冗余量。仿真结果表明,该路由协议的网络生存期、数据分组平均端到端时延以及控制分组百分比较传统的定向扩散协议及最小跳数路由协议有明显改善。 For static strip distribution characteristic of wireless sensor networks nodes used in underground pressure monitoring system,the minimum hop count routing protocol was taken as a research object and improved in route creation phase,data transfer phase and maintenance update phase.Animproved routing protocol named the minimum hop count based on node energy classification was put forward.The improved routing protocol reduces control group and redundancy of data transmission path by grading the node energy.The simulation result show that the improved routing protocol has obvious advantages in extending life period of network,reducing average end delay of data packet and reducing percentage of control packets over the traditional directed diffusion routing protocol and the minimum hop count routing protocol.
