Disturbance forbearance network, well known as Disruption Tolerant Network (DTN) has wide scope today in internet world because of its ability to transfer the message even when the connection is broken down. DTN uses simple store and forward concept, which can be also called as opportunistic network since the sender node may not possess direct contact with the receiver. DTNs have several applications in various areas like interplanetary networking, military networking, etc. In this paper, the authors discuss about few well known applications of disturbance forbearance network, few well known techniques like ferrying, multi-hoping, delivery probability.
