Burst Aware Forecasting of User Traffic Demand in LEO Satellite Networks
Yekta Demirci, Guillaume Mantelet, Stephane Martel +2
In Low Earth Orbit (LEO) satellite networks, Beam Hopping (BH) technology enables the efficient utilization of limited radio resources by adapting to varying user demands and link…
Resilience Through Escalation: A Graph-Based PACE Architecture for Satellite Threat Response
Anouar Boumeftah, Sarah McKenzie-Picot, Peter Klimas +1
Modern satellite systems face increasing operational risks from jamming, cyberattacks, and electromagnetic disruptions in contested space environments. Traditional redundancy strat…
Online Convex Optimization for On-Board Routing in High-Throughput Satellites
Olivier Bélanger, Jean-Luc Lupien, Olfa Ben Yahia +3
The rise in low Earth orbit (LEO) satellite Internet services has led to increasing demand, often exceeding available data rates and compromising the quality of service. While depl…
PIKAN: Physics-Inspired Kolmogorov-Arnold Networks for Explainable UAV Channel Modelling
KürÅat Tekbıyık, GüneÅ Karabulut Kurt, Antoine Lesage-Landry
Unmanned aerial vehicle (UAV) communications demand accurate yet interpretable air-to-ground (A2G) channel models that can adapt to nonstationary propagation environments. While de…
A User Centric Group Authentication Scheme for Secure Communication
Oylum Gerenli, Gunes Karabulut-Kurt, Enver Ozdemir
Group Authentication Schemes (GAS) are methodologies developed to verify the membership of multiple users simultaneously. These schemes enable the concurrent authentication of seve…
Joint Satellite Power Consumption and Handover Optimization for LEO Constellations
Yassine Afif, Mohammed Almekhlafi, Antoine Lesage-Landry +1
In satellite constellation-based communication systems, continuous user coverage requires frequent handoffs due to the dynamic topology induced by the Low Earth Orbit (LEO) satelli…
