Power efficient event detection scheme in wireless sensor networks for railway bridge health monitoring system

Abstract

Railway Bridge Health Monitoring is of paramount importance as damages in bridges can lead to huge casualties and have huge underlying economic consequences. This monitoring can be performed using wireless sensor networks. In this paper, we propose an event detection strategy for wireless sensor networks deployed for railway bridge health monitoring. Our proposed scheme takes care of different constraints of sensor networks and efficiently uses the limited resources of sensors like battery power and memory. Theoretical and experimental results show that our proposed scheme can greatly increase the service lifetime of sensor networks and aid in automating the bridge health monitoring.
