A Study on Geographic Routing Protocols in Delay/Disruption Tolerant Networks (DTNS)
Abstract
Delay/Disruption Tolerant Networks (DTNs) have been attracting great interest from research community, where data communication naturally does not require contemporaneous end-to-end connectivity. Although suffering from a large variation of network topology, numerous previous routing protocols proposed for DTNs still make effort on qualifying delivery potential, via network topology information. Geographic routing is an alternative, by relying on the geographic information instead of topological information. In the literature, since this technique branch has not been extensively investigated in DTNs, our article identifies the motivation and challenges forapplying geographic routing in DTNs. Also, we highlight the future research directions for this branch
