NDN in large LEO satellite constellations
Proceedings of the 8th ACM Conference on Information-Centric Networking, 2021Large low Earth orbit (LEO) satellite constellations are intended to provide global low-latency high-bandwidth Internet connectivity. Due to their large scale and high mobility nature, networking is a big challenge. In this paper, we investigate applying Named Data Networking (NDN) to this scenario.

Satellite Diversity to Mitigate Jamming in LEO Satellite Mega-Constellations
2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021With current large-scale deployments of low-earth orbit (LEO) satellites, the demand for data services provided by these satellite systems is expected to increase rapidly in the near future. To provide high-quality, high-rate data services it is essential to incorporate resiliency features, such as mitigation against potential jamming threats, to these

Satellite constellations for a multiple LEO satellite network
Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 1993AbstractRecently, research has been very active in communication networks that could service the entire globe by using multiple, low, earth‐orbiting satellites. This has been spurred on by progress in the field of digital communication technique, technical advances of satellite launching, and a decrease in the costs of small‐sized satellites.In this ...

A Study of Constellation for LEO Satellite Network
22nd AIAA International Communications Satellite Systems Conference & Exhibit 2004 (ICSSC), 2004For a LEO constellation system, it is important to optimize the orbit parameters to maximize the quality of communication service. At the Next-generation LEO System (NeLS) Research Center, the LEO parameters were evaluated for a mobile satellite communication system. A 2π constellation was selected to maintain a stable inter-satellite link (ISL).

LEO satellite constellation performance analysis
Proceedings of MILCOM '93 - IEEE Military Communications Conference, 2002To date, radio frequency crosslinks have been the preferred communication medium for low Earth orbit (LEO) satellite networks. However, laser crosslinks in satellite constellations introduce many new and interesting research problems not addressed in these conventional methods.

Computing call-blocking probabilities in leo satellite constellations
IEEE Transactions on Vehicular Technology, 2003We present an analytical model for computing call-blocking probabilities in a low Earth orbit (LEO) satellite network that carries voice calls. Both satellite-fixed and Earth-fixed constellations with interorbit links and handoffs are considered. We assume a single beam per satellite.
