Networks are going where no networks have gone before, and delay/disruption tolerant networking (DTN) technology is leading them there. This book shows you how to engineer a robust networking scheme for environments so extreme that ubiquitous, end-to-end connectivity is not possible. You learn why an overlay network, a delay-tolerant transport layer, or a point-to-point protocol is needed to handle this type of intermittent connectivity. This cutting-edge resource helps you determine how DTN protocols will be of use when designing a network that cannot support TCP-based applications. The book takes an application-based approach with a particular focus on sensor networks and deep-space communications. In addition to examining the generic causes of delay and disruption, this practical volume also looks in detail at implementation efforts, routing, security, and many other details of DTN protocols and applications.
