Research and Design of the Clock Synchronization for the Bridge Health Monitoring System Based on Wireless Sensor Network

Abstract

This paper constructs a bridge health monitoring system based on Wireless Sensor Network. In order to detect and obtain the bridge's status information, we have studied the clock synchronization problem between the sensor nodes in wireless sensor network of the bridge health monitoring system. The clock synchronization simulation verifies the design of asymmetrical clock synchronization algorithm in the wireless sensor of the bridge health monitoring system is valid and reliable. The simulation results show that this clock synchronization algorithm can realize the clock synchronization and be able to monitor real-time bridge conditions.
