摘要：Delay/ Disruption Tolerant Networking (DTN) program is an emerging technology that can facilitateaccess to information when secure end-to-end paths cannot exist.Disruption tolerant network is a different type ofwireless network. It is an intermittently connected mobile network. Delay tolerant network adopts a store carry-andforwardmechanism, of which all the participants are assumed to cooperate with one another in message delivery, toovercome the challenges of the intermittent connection and the time-varying network topology. Here, at maximum timethere does not exist a clear way from source to the destination. It also has a limitation in network resources. The DTNallows communication only if it is in the communication range. Because of this constraint there is a chance of dippingthe received packets by the selfish or malicious nodes. Finally this leads to attacks. Malicious nodes within a DTN mayattempt to delay or destroy data in transit to its destination. Such attacks include dipping data, saturating the networkwith extra messages, humiliating routing tables, and imitating network acknowledgments. Misbehaving nodes consumenetwork resources, plummeting its concert and accessibility; therefore they constitute an important problem that shouldbe considered.Many approaches are proposed to solve the problems which are occurred in DTN.In this paper I amfocus on delay tolerant network architecture and its working and also focus on malicious or selfish node behavior.
