Data Transfer Protocol in Bridge Structural Health Monitor System using Wireless Sensor Network

In this paper, a structure health monitor (SHM) system for the bridge is introduced, of which wireless communication and embedding techniques are deployed. After summing up the wireless communication techniques and time synchronization requirements in practical application, a data transfer protocol based on clock synchronization and reliability in wireless sensor networks is proposed, and then its time synchronization error analysis are discussed. All of the related work contributes to the development of a commercial, cost-effective, and reliable SHM system
