Wireless Distributed Network System for Relief Activities after Disasters - A Field Experiment for Channel Setting and a System for Information Exchange among Shelters

Safety information of evacuees is the most important information for relief activities in disasters. We have discussed about required conditions for computer systems destined for supporting effective relief activities after disasters. In addition, on the basis of this discussion, we also have proposed a network construction algorithm and have performed preliminary evaluation about the installation locations among wireless stations and wireless link connectivity. In this paper, we report the results of preliminary evaluation of the performance of information sharing algorithm ADES. In addition, this paper introduces an improved system called ADES-Plus. ADES-Plus system employs information management function by an existing database. Furthermore, in accordance with the required speed of information sharing, we add a function that enables flexible processings. These new functions are confirmed to be work well through computational experiments.
