Abstract:

The fundamental characteristics,architecture,application fields,active academic research institutions and their main works of delay and disruption tolerant networks(DTN)were briefly introduced.Then the status of research and development including DTN routing protocols and transport protocols was presented in detail with analysis and comparison,and open research issues were also discussed.Furthermore,the simulation tools of DTN were analyzed and compared.Finally,the research directions of DTN were pointed out to motivate new research and development in this area.

Key words: delay and disruption tolerant network, challenged network, architecture, routing protocol, transport protocol, simulation tool
