Abstract: Safety information regarding evacuees is the most important information for relief activities carried out after disasters. We have previously discussed the requirements for computer systems designed for supporting effective relief activities after disasters. In addition, on the basis of this discussion, we have also proposed a network construction algorithm and have performed a preliminary evaluation regarding the installation locations of wireless stations and wireless link connectivity. In this paper, we report the results of a preliminary evaluation of the performance of the information-sharing algorithm autonomous data exchange system (ADES). In addition, this paper introduces an improved system called ADES-Plus. The ADES-Plus system employs information management functions using an existing database. Furthermore, in accordance with the required speed of information sharing, we add a function that enables flexible processing. The effective operation of these new functions is confirmed through computational experiments.

Keywords: information systems; disasters; wireless networks; information sharing; disaster information; disaster relief; emergency relief; safety information; evacuees; autonomous data exchange; information management; emegency management; disaster management.
