Abstract

In recent years, temporary network construction using Delay Tolerant Networking (DTN) has attracted attention as a preparation for communication infrastructure failures that may occur due to disasters. DTN is a technology that allows data packets to be delivered late due to temporarily failure of networking. We have proposed an aggregated message ferry method to improve performance of data transfer with the message ferry method which is the routing method of DTN. In our proposed method, each data are aggregated in advance to a node with high probability to communicate with the ferry node. However, our proposed method has a problem that data cannot be transferred to a destination node if the number of hops on a route is large when data are aggregated. In this paper, we propose a new message ferry method enables each node to establish a route in order to increase the number of data arrivals by shortening paths. In the proposed method, each node attempt to transfer data to a node that is included in the communication route to a ferry node. To show the effectiveness of our proposed method, we compare our proposed method with a conventional method in terms of hop count and data arrivals. Simulation results showed that our proposed method achieved higher data arrival number and hop count reduction than the conventional method.
