Abstract

Scientists and space explorers now are looking for a way to communicate almost instantly beyond Earth. The next phase of the Internet will take us to far reaches of our solar system, and lay the groundwork for a communications system for a manned missions to Mars and planets beyond. If we ever want to find out more about other planets, we will need a better communication system for future space missions. Today, communication in space moves at a snail's pace compared to communication on Earth. Increasingly, network applications must communicate with counterparts across disparate networking environments characterized by significantly different physical and operational constraints than what we find in today's Internet. In general, these environments share a common inability to establish and maintain a low-loss, low-latency, end-to- end communication session. Yet, it is precisely the ability to maintain such a session that is required by most existing Internet-style protocols. We will study the fundamental principles that underlie a delay-tolerant networking (DTN) architecture, that is suitable for the future Interplanetary Internet (as an extreme case) but also for "extreme situation networks" on planet earth (e.g. in developing regions with limited power and telecommunication infrastructure, or, in natural disaster areas).
