An improvement of disaster information system for local residents

Abstract

It has been pointed out that when people lack the information needed in the event of a disaster, such as a disastrous earthquake, this could lead to social chaos, including unwanted rumors and outrages, or could disrupt rescue and relief activities. In our prior study, we established a service infrastructure with an autonomous wireless network, aiming at providing services to collect and deliver disaster information. The system consists of many small sub systems. 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. In this study, we improved and extended the system so that it may meet more nearly actually. © 2013 Springer-Verlag Berlin Heidelberg.
