Distributed autonomous system for victims of the earthquake: Disaster information system for local residents

In a time of huge disaster such as earthquake, information needs increase among victims and rescuers. Social ferment rises within afflicted area, and the damage is spread, if the needs of information are not satisfied. In this research we developed an information system for disaster victims as a distributed autonomous system using a wireless network. This system consists of many sub systems. These sub systems are robust for collecting disaster information because they are small and simple. An authorized user can register information using one of the sub systems that is working correctly. Asynchronously, they search another sub system via wireless network, and then they communicate to each other in order to exchange information they have. As a result, the information will be shared within a wide area by those processes like a bucket brigade.
