An anatomy on routing in delay tolerant network

Delay Tolerant Network (DTN) is primarily and specifically a class of MANET that is challenged. The working principle of DTN illustrates the mechanism to store information and carry it till some capable node is found and then a message is forwarded. This kind of implementation has found application areas like sparse and constrained networks. This paper explains the design specification issues of DTN and its suggested implementation strategies. Comparison of various routing protocol proposed and their limitations are stated. The performance parameters like connectivity, its structure, high mobility and few resources. Lastly, the paper is concluded with the areas in which the future research work can be done, providing a clear vantage point to the other interested researchers in this field.
