Many cities or towns are located in mountain and sea areas, and these areas would be isolated from others because of the disconnection of networks or transportation if a large scale disaster should happen. In this paper, Delay Tolerant Networking (DTN) based on the Data Triage Method with the user policies and the Autonomous Flight Wireless Nodes (AFW) based on autonomous flights and data deliveries are introduced. 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). That is, the AFW automatically flies for seeking possible wireless nodes, send and receive disaster information by the proposed DTN routings, and return to the possible stations that wireless charge units are equipped when the battery needs to charge. Then, the implementations and the field experiments are discussed for the effectiveness of the proposed methods.
