A backup routing with wireless sensor network for bridge monitoring system

This paper proposed and implemented an efficient and reliable backup scheme for bridge monitoring systems. It is mainly using a wireless sensor network (WSN) to gather the related environmental parameters and to transmit the numerical data to the gateway through multiple-hopping relay. And then it further stores data in the back-end database for the professional monitoring staffs to analyze and study. Besides, the proposed backup scheme could also ameliorate the inconvenience to add or remove sensor nodes in an existing wired bridge monitoring network. At last, the feasibility of the proposed scheme is verified by experimental results.
