Delay Tolerant Network (DTN) is one of the key areas in wireless communication. Characteristics of delay tolerant network include intermittent connectivity, discontinuous connection from source to destination. It is an approach to computer network architecture that seeks to address the technical issues of heterogeneous network architecture which lack continuous network connection. This layer handles long delays, disconnectivity and high lose rate due to disruption. Data will be stored in persistent storage on DTN device and it will be forwarded to other node where the link is available.
