The research of routing forwarding strategies in DTNs based on convergence point

Abstract

DTN is developed as an emerging network technology which is mainly used in network with long waiting time, intermittent connectivity, and other extreme environments network. It has be favored in the military, transportation, marine monitoring, wildlife tracking, satellites communications and have been applied in some aspects. Currently, there is a lot of research about the DTN. The study includes three hot issues: the routing nodes, DTN-based mobility model and the data distribution and retrieval. To better solve the problem of data distribution and retrieval in DTN, an improved routing algorithm is proposed in this paper. © 2013 Springer-Verlag.
