英文摘要: Wireless sensor network (WSN) is one of key technologies in Internet of Things (IOT), which can be applied in many areas, such as structral monitoring, environmental monitoring, and smart transportation et al. Calibration is one of the most critical problems in WSN. The WSN-based structural monitoring system may encouter the obstacles, such as signal discontinuity, sparse deployed sensors, time-variant calibration parameters and nonlinear calibration functions. Against such obstacles, the calibration models will be proposed. This proposal will also study the calibration condition and sensor nodes optimization techniques. Finally, the WSN calibration platform will be constructed.
