Abstract
After the East Japan Great Earthquake in 2011, a robust network communication has been one of significant subjects for the study of Disaster Information System. Then, DTN (Delay Tolerant Network) has been focused for the effective methods for such inoperable network circumstances. However, when DTN is applied for the local areas, there are some problems such as message delivery rate and latency because there are fewer roads, cars, and pedestrians than in urban areas. Therefore, we propose the Enhanced Media Coordinate System for DTN to the architecture in order to provide the Data Triage, Node Selection based on its Territory, and Dynamic FEC (Forward Error Correction). In this paper, the proposed Data Triage Methods that provide the data priority by the user policy and the application type is especially explained, and the results of the computational simulation by the GIS map of a Japanese coastal town is reported. Then, the results are discussed for the future studies of DTN for Disaster Information Network System in local areas.
