面向近地表地下空间信息监测的无线传感器网络三维节点部署算法研究

摘要

This paper firstly analyzed the essential characteristics of underground space and introduced the multi-indices constrains of node deployment algorithm in the 3D underground space,and then proposed an adaptive,multi-precision constrains sensor node deployment algorithm based on grid model (AKGM) for near-surface underground space monitoring.It discussed the analysis and simulation for AKGM algorithm from network structure,adaptive,energy consumption,probability of overage and connectivity,degree of overage and connectivity etc.The results show that the algorithm can efficiently solve the three-dimensional sensor node deployment problem for near-surface underground space monitoring and provide theoretical guidance and practical basis for the monitoring of soil environment,intelligent traffic and other underground target.%从地下空间的基本特点出发,提出了地下空间节点部署算法的约束指标,建立了面向地下空间的自适应、多精度约束的节点部署算法.从网络结构、自适应性、能量消耗及覆盖连通性能等方面对算法进行了分析和仿真,结果表明该算法能有效地解决近地表地下空间节点的部署问题,为土壤环境监测、智能交通监测、管道监测及其他地下目标监测提供理论指导和实践依据.
