Monitoring system for landslide disaster by wireless sensing node network

Sensing system to monitor natural disasters faces much hard conditions. Natural disaster occurs suddenly, and damages sensor system. Then, the sensor system should be designed as distributed node network. In addition to that, the network should have some characteristic functions like self-recovery, autonomous operation and effective data transmission in urgent. This paper describes the construction of autonomous sensing node network to recover the damage by landslide disaster and to transmit urgent data effectively. The sensing node network is operated by three mode(initializing mode, measuring mode and urgent mode). By switching these operation modes autonomously, the sensing node network becomes robust system to the loss/insert of sensing node and the dynamic control of data transmission. Finally by some experiments, the effectiveness of operation is shown.
