Studies on Networks for Monitoring Posts Based on Mesh-Type LPWA

The possibility of data collection by a mesh-type LPWA was examined, expecting its use in radiation monitoring during complex disasters and unexpected circumstances. In this study, the Shimane Institute of Public Health and Environmental Science, located next to the Shimane Nuclear Environmental Center, was used as the base for the study. The mesh network connecting the monitoring points around Matsue City and Lake Shinji specified in the disaster prevention plan of Shimane Prefecture was flexibly deployed. As a result, stable communication and flexible network deployment were confirmed. On the basis of the results of this study, a proposal for a monitoring scheme using a mesh-type LPWA is introduced.
