In large-scale disaster such as an earthquake, the existing communications infrastructures may not operate sufficiently.
We have proposed a disaster information system that realizes information sharing among evacuation centers in such a poor communication situation.
In the system, portable storages such as USB memories are used as communication media.
We have proposed content selection algorithms for efficiently transferring disaster information on the system.
In the methods, however, the probability of sending to each evacuation center has been assumed to be uniform.
In this paper, we introduce information that can be used as a nonuniform transmission probability distribution, thereby realizing improvement of transfer efficiency.
We propose the methods to use movement plan of the carrier and the geographical relationship of the evacuation centers to estimate the destination.
We confirmed effectiveness of each method through simulation evaluation of information diffusion and transferring efficiency. |
