Delay tolerant network: routing issues and performance

Abstract

Delay tolerant networks (DTNs) are deployed in long distance data communications where delay is permissible like in interplanetary networks (IPNs). For the transfer of messages in a DTN, various routing schemes have been proposed but there has not been an umpteen amount of work related to their comparisons. Therefore, a study of the routing techniques, issues in DTN connectivity and performance analysis of routing algorithms in DTN have been showcased in the current work. This analysis would help the researchers in identifying the most efficient routing scheme amongst well known routing algorithms.
