Dynamic monitoring of a tunnel-like masonry structure via WSN

This paper reports an application of wireless sensor network technology to the long-term monitoring of a historic masonry tunnel-like structure located in Italy. The monitoring was performed within the activity of a research project aimed at providing a general framework to check the structural health of heritage structures and to real-time detect any potential damage that may compromise their safety. The tunnel-like structure was selected being, to the best of authors' knowledge, a challenging experiment both for the type of structure itself and for the technical solution to be employed for installing the monitoring system. This paper, after a brief description of the installed monitoring system and the design of the sensor layout, summarizes the lesson learned after one year of monitoring.
