Position paper: Design concept of ad-hoc Information Network System for disaster mitigation

We have gone through national crises caused by earthquakes and tsunamis. Through these experiences we have established advanced communication systems and advanced disaster medical response systems. However, Japan was devastated by the Great East Japan Earthquake occurred on March 11^th, 2011. Huge tsunamis swept a vast area of Tohoku causing a complete breakdown of all the infrastructures including telecommunications. Communication of emergency information was limited causing a serious delay in the initial rescue and medical operation. For the emergency rescue and medical operations, it is the most important to identify the number of casualties, their locations and states and to dispatch doctors and rescue workers from multiple organizations. In the case of the Tohoku earthquake, the dispatching mechanism and/or decision support system did not exist to allocate appropriate number of doctors and locate disaster victims. Even though the doctors and rescue workers from multiple government organizations have their own dedicated communication system, the systems are not interoperable. In the area of the disaster management, introduction of cutting edge ICT is urgently needed. In this paper, we propose a design concept of Emergency Temporal Information Network System designed in a system of systems in Acute Stage of Large-scale Disasters Damage Mitigation.
