Abstract
The Delay Tolerant Networks (DTN) is well known as the resilient routing protocol for robust network
conditions such as the situation just after the large scale disasters. This paper introduces the
implementations of the DTN routing with the Data Triage Method and the group priority transmission
by using the Device-to-Device (D2D) communication API on the android smartphones in order
to realize the assumed Disaster Information System. In the proposed methods, the user policy is
introduced for the Data Triage Method from the evacuators messages and the static body detections,
and the historical locational information is introduced for the priority node selection method by the
implementations using the D2D API. Then, the evaluations of the prototype system are reported in
this paper, and the results shows the affectivity of the prototype systems because the delivery rates of
the high priority messages reached to 100 percent within one second in the experiments.
