A SURVEY ON THE RECENT DEVELOPMENTS IN DELAY TOLERANT NETWORKING AND ITS APPLICATIONS FOR INTERPLANETARY INTERNET

摘要

Delay Tolerant Networking is the current hotspot in the area of deep space communication. DTN uses a standard message format called Bundle Protocols (BP) to transfer any data. Till date, very few research works have been done to test the performance of these Bundle Protocols. This survey paper brings out the current architecture of the InterPlaNetary (IPN) Internet, the features of the Bundle Protocols, and a real time scenario describing how these features of the BPs add up resulting in the efficient transmission between two network nodes in terms of packet transfer, security and other parameters. The recent experiments conducted on space DTN is also discussed in this paper. A survey on the current IPN architecture also reveals the necessary improvements that must be made at all the layers of the architecture to make it more reliable, efficient than the present time.
