Variable Data Flow Management in Wireless Sensing Network for Landslide Disaster

Sensing systems to monitor natural disasters face many hard conditions. Natural disasters occur suddenly, and damage the sensor system. Therefore, the sensor system should be designed as a distributed node network. In addition to that, the network should have some characteristic functions, such as self-recovery, autonomous operation and effective data transmission. This paper describes an effective data flow management in wireless sensing node network for landslide disasters. The sensing node network is operated by three modes (initializing, measuring and urgent). By switching these operation modes autonomously, the sensing node network becomes a robust system (loss/insert) of sensing node and the dynamic control of data transmission. Finally, the effectiveness of the operation is supported by some experiments.
