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

International 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

International 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

International 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 ...

Towards Sustainable e‐Waste Practices: A Value‐Belief‐Norm Analysis of Mobile Phone Disposal in Ghana

Sustainable Development, EarlyView.
ABSTRACT Electronic waste (e‐waste) from mobile phones is a growing concern in resource‐constrained contexts, where limited infrastructure and regulatory enforcement promote reliance on informal systems. In Ghana, a rapidly expanding digital market, e‐waste accumulation poses significant environmental and social challenges.
