Routing Approaches in Delay Tolerant Networks: A Survey
R. J. D’Souza, Johny Jose · International Journal of Computer Applications · 2010
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.
