Outline of Final Research Achievements

In this research, we establish a non-volatile networking technology which enables smooth communication even when network is seriously damaged due to quite heavy load of network traffic or power failure under the large-scale disaster situation. To cope with the large-scale disaster situation, DTN (Delay Tolerant Networking) technology was proposed. DTN makes it possible to transfer data bundle by storing and forwarding at relay node. By utilizing DTN, some disaster-resilient communication schemes are proposed, but due to its one-way data transfer nature, it is difficult to utilize DTN to bi-directional communication such as safety confirmation or information retrieval. To solve the above problem, we develop the non-volatile networking technology. The non-volatile networking enables a user to disconnect a mobile terminal from network while waiting the response from a server by keeping both a request and a response on network.
