Abstract:

Structural Health Monitoring (SHM) in historical buildings is achieved by sensing the structure's ambient vibrations. Technological advances in Wireless Sensor Networks (WSN) provide potential for non-intrusive monitoring approaches. A common challenge among WSN applications is the synchronization of the participating sensors, in order to collect reliable information. The current work proposes a broadcast-based lightweight synchronization process which is tested for its effectiveness in a small scale multi-hop ad-hoc network under lab conditions. The two experiments conducted in the context of this study, show that the performance of the synchronization initially places timers within a range of zero to three milliseconds and explore the effect of sensors' clock drifts and the resulted accumulation of synchronization deviation over time.
