摘要

In order to construct the wireless underground sensor network of the stadium,guarantee the temperature and pho?toelectric signals of the intelligent control stadium,realize the intelligent stadium,the hierarchy and position based geographic routing decision?making mechanism of the stadium′s wireless underground sensor network is proposed. The topology structure model of the wireless underground sensor network was built,in which the directional flooding mechanism based on hierarchy is used to establish the routing protocol. The node deployment optimization of the wireless underground sensor network was per?formed according to the hierarchy,density and residual energy of nodes. The routing detection was designed according to the net?work hierarchy and underground geographic location. The performance was tested with simulation experiment. The experimental results show that the wireless underground sensor network of the stadium has good balance of energy consumption,low end?to?end time delay of the network node,and high packet accurate transmission rate.%构建体育场馆的无线地下传感器网络，保障智能控制场馆的温度和光电，实现构建智慧体育场馆，提出基于层级和位置的体育场馆无线地下传感器网络地理路由决策机制。首先构建无线地下传感器网络的拓扑结构模型，采用基于层级的定向泛洪机制进行路由协议构建；然后根据节点的层级、密度和剩余能量进行无线地下传感器网络的节点优化部署，根据网络的层级和地下地理位置实现路由探测设计；最后通过仿真实验进行性能测试。实验结果表明，该体育场馆无线地下传感器网络具有较好的能耗均衡性，网络节点端到端的时延较低，数据包的准确传输率较高。
