Abstract

Applying wireless sensor networks for infrastructure monitoring bas gained interest in recent years. Wireless sensor networks can continuously monitor infrastructure condition and report any changes that may lead to failure. The collected data can be used for the analysis of infrastructure life expectancy and safety index, therefore optimizing maintenance procedures for improved cost-effectiveness. This paper discusses the implementation and field test of a wireless sensor network for infrastructure monitoring. A lest bed was established in a laboratory to collect the strain information, using both concrete and metal specimens for tbe experiments, and the wireless sensor network system was implemented in the field to monitor a bridge structure. Issues investigated include practical implementation such as sensor placement, communication distance, operation in a harsh environment, energy efficiency, and battery lifetime for different operation modes. The paper also examines feasibility, challenges, and recommendations for large-scale deployment in infrastructure monitoring.
