In replace of human labor, wireless sensor networks (WSNs) are increasingly being utilized to perform structural health monitoring of underground tunnel. Due to its complex environment, the deployment of sensor nodes poses a big challenge to related staff. How to use the optimal number of sensor nodes deployed in the underground tunnel to obtain a satisfactory monitoring is our main consideration. In this paper, we propose a deployment strategy based on the optimal index to provide guidelines for sensor node placement. The objective of the strategy is to put sensor nodes in a proper site to gain maximum sensing information, thus eliminating redundant sensor nodes as well as saving costs.

通过无线传感器网络进行地下隧道监控的最佳传感器位置

在取代人工方面，无线传感器网络（WSN）越来越多地用于执行地下隧道的结构健康监测。由于环境复杂，传感器节点的部署对相关人员构成了巨大挑战。我们主要考虑如何利用部署在地下隧道中的传感器节点的最佳数量来获得满意的监控。在本文中，我们提出了一种基于最佳索引的部署策略，以为传感器节点的放置提供指导。该策略的目标是将传感器节点放置在适当的位置以获取最大的传感信息，从而消除冗余的传感器节点并节省成本。
