DTN
Delay Tolerant Networks
Part 1: Introduction In communication field, networks become more popular and routing protocols face multiple challenges. They have first to minimize delay then maximize throughput.
- Internet vs. DTN DTN routing involves message replication. They are therefore useful to operate over long distances as for telecommunications space 1 for which latency reaches sometimes hours or even days On another hand we have Internet which is based on packet forwarding.
Part 2: - DTN Architecture and Bundle Protocol
Part 3: Application Areas
- Opportunistic/social networking
- VANETs
- Habitat monitoring
- DTN-based Social Network
- Low cost communication solutions
Part 4: Conclusion
Some of characteristics of Delay Tolerant Networks are: - No end-to-end path - Intermittent connectivity - Long delay - They are also dynamic
