ABSTRACT
Delay-tolerant networks (DTNs) can be used in disaster-hit areas where wired and wireless communication is badly hampered due to natural or manmade calamities. DTNs can be used in border regions or cross-border areas which are not easily accessible to human beings either due to poor geographical terrain or extremely low temperature, like in the Siachen Glacier. DTNs can be used for the preservation of the plants and trees in forests, thereby preserving the biosphere. DTN contacts can also be used for the preservation of birds and wildlife in national parks or reserves by counting them through keeping track of their movements. DTN contacts can be applied to carrying out communication between countries on the ocean/seabed, thereby creating an underwater oceanic marine network. DTNs can be used to provide communication facilities in difficult terrain where it is not feasible to set up wired and wireless communication, like in mountainous regions, or in desert regions.
