Proposal of Connectivity Support Methods with Autonomous Flight Wireless Nodes for Never Die Network

When an ultra large disaster such as the East Japan Great Earthquake occurs, communication networks would be severely disconnected by the damages of servers and network devices. Especially, in the early stage of a disaster, disaster information such as life safety and evacuation shelters becomes extremely important for the people. For the sake of such situations, Never Die Network (NDN) is one of the resilient network approaches based on the robust connectivity and quick recovery. In this paper, we propose the additional data delivery supports for the NDN by using the autonomous flight drones. In the proposed system, the drone with wireless interfaces is applied, and it actively supports the proposed DTN routings for the Disaster Information System (DIS). Then, the evaluation of our proposal methods and future study is discussed.
