Basic Review of DTN Routing Protocol Approaches

A DTN is a network of smaller networks. It is an overlay on top of special-purpose networks, including the Internet. DTNs support interoperability of other networks by accommodating long disruptions and delays between and within those networks, and by translating between the communication protocols of those networks. In providing these functions, DTNs accommodate the mobility and limited power of evolving wireless communication devices. DTNs were originally developed for interplanetary use, where the speed of light can seem slow and delay-tolerance is the highest need. However, Delay tolerant networks may have extreme most diverse applications in the Earth, where disruption-tolerance is the highest need. Delay tolerant networks Routing has thus stimulated since it must handle partitioning of the network, long delays, and also dynamic topology in such networks. In current years, social-based methods, which attempt to the exploit social performances of the Delay tolerant network nodes to make a suitable routing decision, have drawn tremendous interests in the Delay tolerant networks routing design. In this paper define about routing protocol classification, existing network information etc.
