Mobile Cloud Computing on Delay Tolerant Network Protocol

From the geological condition of Japan Island, many serious disasters such as earthquake, tsunami and typhoon occurred in history. A huge numbers of people, buildings and communication infrastructure are completely damaged. More resilient oriented network infrastructure that does not stop under challenged communication environment is strongly required. In this paper, we propose a mobile cloud computing system which can flexibly deal with failures of the network communication capability and information servers and respond to rapid change of information network condition. We construct the disaster information system based on the cloud computing technology. In addition, we develop a dynamic allocation of disaster server resources in accordance with the load change on the system in the disaster areas. Also, by introducing a mobile clouding with DTN protocol, our system can realize rapidly sharing disaster information even though the communication breakdown area occurred.
