Wireless sensor networks (WSNs) are one of the most able technologies in the structural health monitoring (SHM) field. Through\r\nintelligent, self-organising means, the contents of this paper will test a variety of different objects and different working principles\r\nof sensor nodes connected into a network and integrated with data processing functions. In this paper the key issues of WSN\r\napplied inSHMare discussed, including the integration of different types of sensors with different operational modalities, sampling\r\nfrequencies, issues of transmission bandwidth, real-time ability, and wireless transmitter frequency. Furthermore, the topology,\r\ndata fusion, integration, energy saving, and self-powering nature of different systems will be investigated. In the FP7 project ââ?¬Å?Health\r\nMonitoring of OffshoreWind Farms,ââ?¬Â the above issues are explored.
