Due to the development of the wireless communication technologies, wireless sensor networks (WSNs) are becoming more and more important in Internet of Things (IOT). In this paper, we proposed a design of a WSN for the enormous constructions structural healthy monitoring. Based on the analysis of the past project about the WSN for the highway healthy monitoring, we propose a novel design that can be used to guide the design of the future WSNs for the structural healthy monitoring. The focus of the design is the hardware design and the network layer design between the hardware and the users. In ...
