Wireless Sensor Networks and Application Research Based on ZigBee Technology

The wireless sensor networks (WSNs) are the hotspot research of current sensor technology.Much attention are focused on the design for wireless sensor network node based on ZigBee technology,the development of the sensor node' s hardware and software and its structural health monitoring application system.A structural health monitoring system based on the developed ZigBee node is built by the pattern matching method.The structure health monitoring system is able to monitor the strain distribution and the con- nection bolt loosing on the structure.
