Mobile Cloud Computing by In-vehicle Servers Based on Delay Tolerant Network Protocol

Serious disasters have been annually occurred in Japan. Particularly, in the Great East Japan Earthquake that occurred on March 11, 2011, the communication infrastructure was seriously damaged over wide areas. Due to such situation, more resilient network infrastructure that does not stop under challenged communication environment is required. In this paper, we propose a disaster information system that can flexibly deal with critical network connectivity. In order to achieve this purpose, we develop a dynamic allocation of server resources in accordance with the load changes on the system so that it is possible to take full advantage of the servers and network resources in the disaster areas. Also, by introducing mobile cloud computing and DTN protocols, our system can share widely disaster information even if the communication breakdown occurred in the area.
