      • Distinction of Landslide by Monitoring Acceleration to Autonomous Node In Wireless Sensing Network

        For monitoring natural landslide disaster, wireless sensing node network is so effective system. The sensingnode is constructed by some sensors (acceleration, soil moisture, GPS and so on), data processing unit (micro processor)and wireless communication unit. The network topology we have constructed is mesh type. In the system, at sensinglandslide, the node will transport the information to host system through the node network by using wirelesscommunication. Generally, in natural field, the landslide is sensed as the changing of acceleration. But, it is sodifficult to distinguish the landslide obviously. The acceleration of the sensing node will change by not only thelandslide disaster but also collision with several hard blocks like stones. This paper describes the distinction method oflandslide disaster by using only the signal of acceleration sensor mounted in the sensing node. The method focuses thetime transition of frequency distribution of the acceleration signal. Observing the time transition, the situations ofsensing node have been distinguished.
