R. J. D'Souza, Johny Jose . Routing Approaches in Delay Tolerant Networks: A Survey. International Journal of Computer Applications. 1, 17 ( February 2010), 8-14. DOI=10.5120/370-557
Delay Tolerant Networks (DTNs) have evolved from Mobile Ad Hoc Networks (MANET). It is a network, where contemporaneous connectivity among all nodes doesn’t exist. This leads to the problem of how to route a packet from one node to another, in such a network. This problem becomes more complex, when the node mobility also is considered. The researchers have attempted to address this issue for over a decade. They have found that communication is possible in such a challenged network. The design of routing protocol for such networks is an important issue. This work surveys the literature and classifies the various routing approaches.
