IDLB: An SDN‐Based Load‐Balancing Routing Protocol for Autonomous Satellite Constellation Networks

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Routing in satellite constellation networks with intersatellite links has become an important aspect to enable broadband Internet access and to integrate into terrestrial networks. However, their dynamic characteristics and large physical size require specifically tailored solutions.

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Advanced Fade Mitigation Techniques for Q/V Band SATCOM Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Adaptive fade mitigation techniques, such as smart gateway diversity (SGD), are essential in addressing atmospheric fading affecting the operation of high throughput and very high throughput satellite systems at Ka‐band and beyond. Specifically, the Q/V‐band, offering up to 5 GHz of available spectrum, is very attractive for future high data ...

Dynamic Resource Allocation for LEO Satellite Systems Under Heterogeneous Traffic Distributions

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes an efficient resource allocation scheme for low Earth orbit (LEO) satellite systems. Taking into account the unique characteristics of LEO systems for 6G communication services, we introduce a dynamic bandwidth and power allocation scheme specifically designed to accommodate highly heterogeneous traffic distributions.

Estimating Rain‐Specific Attenuation at Extremely High Frequencies From Disdrometer Measurements at Various Climate Zones in the US

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity
