Abstract

When there was the East Japan Great Earthquake in 2011, many areas were isolated by the high congestions and the disconnection of cellular phones or Internet. DTN (Delay Tolerant Networking) is one of effective methods for Disaster Information Network System, but the delivery rate and latency are pointed out of the problems of DTN. Besides, since there are fewer roads or pedestrians in local area, it is considered that these problems become worse than the urban areas. In this paper, we introduced DTN with autonomous directional antenna control for wireless network based Disaster Information Network System, and the simulation is held by the map of a Japanese local area. The results show the improvement of DTN in local areas, and they are discussed for the future studies.
