Abstract (in Japanese) (See Japanese page) 
(in English) People recognized that information sharing at the time of a disaster of safety confirmation system , rationing of goods and so on was important. On the other hand, People recognized the problem that it's difficult to communicate information to residents of all situations when communication infrastructure is destroyed by a disaster. We have developed the information station for disaster prevention, which achieve information delivery between safe shelters. In our study, we have proposed the information delivery system, which achieves information sharing by using device-to-devices information sharing with Delay/Disruption Tolerant Networking (DTN) instead of communication infrastructure. When we adopt Epidemic broadcast, which is the most popular routing algorithm, in this system, amount of delivery information in unit time becomes small in inverse proportion to the number of safe shelters. To solve this problem, we have proposed the routing using Geographic information of the destination. Our algorithm restricts a delivery destination. We have showed proposed method can deliver the information earlier than conventional method through simulations.
