Structural health monitoring and earthquake early warning on 5g urllc network

This work deals with the development of a permanent structural monitoring system for buildings, based on innovative minimally invasive technologies in order to provide information about the structural behavior under normal conditions and especially in the presence of seismic events. The gathered information will be processed through model based and data based approaches, in order to compare and possibly integrate these techniques. Referring to the 5G vision the SHM system can be considered depending on the operational scenario: in the case of data collection and processing from sensors in monitored buildings, considering the high number of sensors installed, it can refer to the mMTC context. Viceversa, during a seismic event or just after it, the use case requires high reliability connectivity and, sometimes, low latency. Those features refer to the URLL context. It seems interesting to evaluate and experiment the ability of 5G network to dynamically adapt to the changing scenario that this use case can provide. Moreover this paper presents an innovative 5G architecture for Earthquake Early Warning that uses SHM system to detect a seismic event and to propagate a message reporting the event detection to all the buildings that may be damaged by the event.
