Wireless Distributed Network System for Relief Activities after Disasters A Construction Policy of Heterogeneous Network Architecture

Safety information of evacuee is the most important for relief activities in disasters. Heretofore, we have been discussed about required conditions for computer systems destined for supporting effective relief activities after disasters. In addition, on the basis of the above, we also have been proposed a network construction algorithm and have been performed preliminary evaluation about the installation locations among wireless stations and wireless link connectivity. In this paper, we discuss more about network architecture using heterogeneous wireless link and development of application model using at shelters in order to step forward for the realization of our network system.
