Routing in delay-tolerant networking

Routing in delay-tolerant networking concerns itself with theability to transport, or route, data from a source to adestination, which is a fundamental ability all communication networks musthave. Delay- and disruption-tolerant networks(DTNs) are characterized by their lack of connectivity, resulting in a lack of instantaneous end-to-end paths. In these challenging environments, popular ad hoc routing protocols such as AODV and DSR fail to establish routes. This is due to these protocols trying to first establish a complete route and then, after the route has been established, forward the actual data. However, when instantaneous end-to-end paths are difficult or impossible to establish, routing protocols must take to a ""store and forward"" approach, where data isincrementally moved and stored throughout the network in hopes that it will eventually reach its destination. A common technique used tomaximize the probability of a message being successfully transferred is toreplicate many copies of the message in hopes that one will succeed inreaching its destination.
