Localization of damage using wireless sensor networks for tunnel health monitoring

Actually, safety and security of structural health monitoring “SHM” take an important area in modern society. That's why, several researchers are interested in this topic. In this paper, we focus on the architecture of tunnel health monitoring based on wireless sensor networks, we try to measure and localize damage vibration using a wireless sensor and civil technique. We choose to implement in the wireless nodes two localization damage methods, the first is MNCDWJE “Mean Normalized Curvature Difference of Waveform Jerk Energy” MNCDWJE and the second is CDPWJE “Curvature Difference Probability waveform Jerk”.These two methods are able to ensure the localization of vibration damage in tunnel or in each other civil structure at real time.
