Pervasive wireless sensor networks for the monitoring of large monumental structures: The case of the ancient city Walls of Siena

In this paper, a solution for the pervasive monitoring of large monumental structures based on the use of Wireless Sensor Networks is presented. In particular, the paper focuses on the case of the Ancient City Walls of the city of Siena, Italy, that still surround the whole historic centre and require a real time monitoring of the cracks present in several points.
