About 70% of the Korea consists of mountain area, during construction of many roads and railroads cut-slopes are inevitably formed. With the rainy season, frost heaving in winter and thaw in spring can cause the rock falls and landslides in the roads. The failure of the slope is increasing every year with damage of car broken, personal injuries and death of the people. To protect people and property from these damages, we need the real-time monitoring system to detect the early response of slope failures. The GMG applied the TRS sensor units in the slopes to monitor the slope in real-time. But with the data lines, the system is vulnerable with the lightening damage. The whole system can be damaged by one lighting. So we propose the Ubiquitous Sensor Network in this paper. With the USN system we can minimize the lightening damage and can monitor the movement of the slopes consistently.
