可存盲区的井下无线传感器网络节点部署研究

Research of deployment of underground WSN node with configurable blind area

在分析现有无线传感器网络节点部署方案和覆盖模型的基础上,针对完全覆盖存在难度大、成本高、节点存在冗余等缺点,提出了一种可存盲区的井下无线传感器网络覆盖模型和节点部署方案,并给出了该方案在井下的具体应用。可存盲区的井下无线传感器网络节点部署方案可根据监测对象的具体情况调节盲区度,从而实现盲区大小的设置。分析结果表明,对于相同的节点数量,该方案比完全覆盖时的覆盖面积大;对于同等面积的监测区域,该方案比完全覆盖时所需的传感器节点数量少,不仅节约了系统成本,还在一定程度上改善了节点冗余度问题。

Based on analyzing deployment and coverage model of existing WSN node, and in view ot disadvantages of difficulty in full coverage, high cost and node redundancy, the paper proposed a scheme of underground WSN coverage model and node deployment with configurable blind area, and introduced its application in mine underground. The deployment scheme of underground WSN node can adjust blind area scale according to actual condition of monitored object and realize blind area setting. The analysis result shows that the scheme covers larger area with the same quantity of nodes as full coverage; in the same monitoring area, the scheme needs less sensor nodes, not only saving system cost but also improving node redundancy problem in certain degree.
