Delay- and Disruption Tolerant Networks (DTNs) are networks subject to arbitrarily long-lived disruptions in connectivity and therefore cannot guarantee end-to-end connectivity at all times. Consequently DTNs called for novel core networking protocols since most existing Internet protocols rely on the network's ability to maintain end-to-end communication between participating nodes. This book presents the fundamental principles that underline DTNs. It explains the state-of-the-art on DTNs, their architecture, protocols, and applications. It also explores DTN's future technological trends and applications. Its main goal is to serve as a reference for researchers and practitioners.

Delay- or Disruption-tolerant networking is an approach to networking architecture that is specifically designed for environments with intermittent connectivity. Like the internet suite, DTN has its own protocols for routing data through a network whose nodes are constantly coming in and out of contact with one another. The main difference between delay tolerant networks and the ‘normal’ internet is that DTNs have a memory component and nodes are able to store data for an arbitrary amount of time, whereas nodes in the internet only relay data and all memory resources are concentrated at the end points of a connection.
