Applications in Delay‐Tolerant and Opportunistic Networks
Teemu Kärkkäinen, Mikko Juhani Pitkänen, Joerg Ott · 2013
The characteristics of delay-tolerant and opportunistic communication require fundamentally different approaches at the network layer for routing and forwarding. The move to message-based communication brings along new opportunities for application protocol design; at the same time, the lack of instant feedback and of instant infrastructure access creates a new set of challenges. This chapter explores these challanges and opportunities. Since application design and development is more about practice than theory, the chapter extensively uses examples from real DTN applications and experiments. It also explores the challenges that face application designers working on DTNs. The chapter introduces typical scenarios and then looks at some of the typical challenges. It then looks in more depth at some of the critical issues including security, legacy system support, and user interfaces. The chapter presents four in-depth case studies that look at different aspects of DTN applications. Controlled Vocabulary Terms delay tolerant networks; Wireless application protocol
