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 Future Wireless Internet

  • Generalized Architecture
  • Space communications as a customer
  • Bundle transport without permanent end-to-end paths
  • Store-and forward
  • Late name resolution
  • Custody transfer
  • Convergence layer concept
  • Routing with different levels of knowledge of network topology, offered load and connectivity graphs over time
