DTN for LEO Satellite Communications

open access: yes, 2011
Satellite communications are an interesting and promising application field for Delay/Disruption Tolerant Networking (DTN). Although primarily conceived for deep space communications and sensor networks, it was immediately recognized that DTN was applicable to satellite environments, in particular to cope with the intermittent channels typical of LEO ...

Network Slicing in LEO Satellite Network

2021 2nd International Conference on Artificial Intelligence and Information Systems, 2021
To solve the problems of LEO (Low Earth Orbit) satellite network, such as insufficient flexibility and low resource utilization, an architecture using network slicing technology is proposed. Then a prototype system based on the Docker platform and DTN (Delay Tolerant Network) is implemented, providing IMS (IP Multimedia Subsystem) network slice ...

Doppler characterization for LEO satellites

IEEE Transactions on Communications, 1998
Mobile ground-based terminals observe significant Doppler on the forward channel when communicating through low Earth orbit (LEO) satellites. This paper deals with the analytic derivation of the Doppler shift measured by a user on the surface of Earth on a signal transmitted by a circular orbit LEO satellite. Two simplifications are performed to obtain

RSVP for LEO satellites

IEEE International Conference on Networks. ICON '99 Proceedings (Cat. No.PR00243), 2005
The Internet Engineering Task Force (IETF) is working on extending the traditional TCP/IP model for supporting multimedia and real-time applications on the Internet. Thus, new protocols have been developed such as the resource reservation protocol (RSVP). At the same time, there has been a growing interest in using low Earth orbit (LEO) satellites.
