Abstract:

Wireless sensor network (WSN) application for bridge structure health monitoring (SHM), requires a scalable time synchronization service enabling data consistency and coordination. This paper describes the Energy-Balanced time Synchronization protocol (EBS), especially tailored for bridge structure health monitoring application. Through analyzing the characteristics of the bridge SHM, we present the especial requirements for designing the time synchronization protocol in WSN for SHM. Following the requirements, the proposed time synchronization protocol utilizes dynamically selecting the maximum reserve energy sensor node as broadcasting node to achieve energy balance among nodes in network. In addition, the EBS protocol fully exploits the wireless broadcast channel property in bridge SHM, so the broadcast communication flow is small. The high precision performance is reached by utilizing MAC-layer time-stamp as in the existing FTSP protocol. Finally, The EBS protocol performance is evaluated and compared to FTSP protocol.

I. INTRODUCTION

In recent years, wireless sensor networks (WSNs) have received a huge attention due to their promising applications in a variety of areas including structure health monitoring (SHM). SHM is a highly active area of research devoted to developing the tools and techniques needed for automatic structural-integrity assessments. Broadly speaking, SHM research attempts to use sensors to localize damage and detect its extent through structural response (via the spatiotemporal patterns of vibrations induced throughout the structure). Advance in WSNs provide opportunities for sensing, wireless communication, and distributed data processing for a variety of new SHM applications.
