ABSTRACT
This chapter presents some practical sensor networks using different kinds of sensor. It addresses some key aspects concerning the fiber Bragg grating (FBG) sensors, the distributed optical fiber sensors and sensor networks, including approaches to applying for structural health monitoring, and some representative applications. The chapter provides the trade-off relationship between the optimized sensor network performance and the number of sensors. To provide enough information for damage detection, a number of transducers are usually used to configure a sensor network. In order to design a sensor network, different kinds of sensors can be used. The efficiency of the sensor network depends on the density of sensors. The sensor networks discussed in the sections that follow include the FBG sensor network and the distributed optical fiber sensor network, providing applications of identification and analysis. The damage diagnosis result showed that all the damage in the monitoring region was covered by the sensor network.
