Information Communication System Consisted of Multiple Unmanned Aerial Vehicles on Disaster

On large scale disasters, such as the Eastern Japan Great Earthquake and Kumamoto Earthquake, due to mud slides of cliff and floodwater of rivers, many disaster areas are physically isolated and relief and support activities of victims become quite difficult. The communication means are also destructed in those areas and cannot transmit the disaster information. In order to resolve those problems, we propose an information communication system which consisted of Multiple Unmanned Aerial Vehicles (UAV). In this system, multiple UAVs have wireless communication units and organize a wireless mesh network in the sky to transmit the information among the isolated areas. Its network configuration and architecture are explained. A prototype system is constructed to evaluate its function and performance.
