Development of a sensor node with impact resistance capability for gathering disaster area information

This paper discusses a wireless sensor node with impact resistance capability. We have been discussing the development of disaster information gathering system utilizing wireless sensor network deployed by rescue robots for underground facility such as metro station. For convenient and efficient deployment of a sensor network, we proposed throwing deployment method. To realize throwing deployment, we developed a wireless sensor node with impact resistance capability for withstanding landing impact. An impact resistance capability and throughput of communication of sensor nodes were confirmed.
