DTN Routing Method Based on Records of Data Transmission Paths

The authors focus on the message ferrying method, which is one of the route selection methods on DTN (Delay/Disruption-Tolerant Networking). In the message ferrying method, mobile nodes called ferry nodes transfer data among clusters in which there are many nodes including sink nodes. In the previous research of the message ferrying method, messages therefore are aggregated in nodes close to routes of ferry nodes. However, in the research, the method for data transferring to nodes in the clusters was not discussed. In this paper, the authors proposed a method that used records of the data transferred paths when data are aggregated to decide a route.
