Research Article Prediction Based Routing With History Based Replication for Disruption Tolerant Network

A delay and Disruption Tolerant Networking (DTN) is an emerging network, which handles communications in extreme environments, like space communications and networking in sparsely populated areas, vehicular adhoc networks and underwater sensor networking. DTN routing issues may appear as a standard dynamic routing problem with extended link failure times. To offset this, researchers investigated routing based on future contacts prediction, taking advantage of nodes' mobility history. Routing is performed over time to achieve eventual delivery using long-term storage at intermediate nodes. In DTN, replication is used in DTN flooding strategies and there are many algorithms to manage multiple message copies and to make those copies. This study proposes a prediction based routing with history based simple replication for DTN routing.
