Cross-Slice Co-Location Risk-Aware SFC Provisioning in Multi-Slice LEO Satellite Networks
Mohammed Mahyoub, Wael Jaafar, Sami Muhaidat +1
We address cross-slice co-location risk in multi-slice low Earth orbit (LEO) satellite edge networks, where virtual network functions (VNFs) from different network slices sharing t…
Two-Tier High Altitude Platform Stations (HAPS) for Exploring Wireless Energy Harvesting
Faicel Khennoufa, Khelil Abdellatif, Halim Yanikomeroglu +3
In sixth-generation (6G) cellular networks and beyond, aerial platforms, such as uncrewed aerial vehicles (UAVs) and high-altitude platform stations (HAPS), are anticipated to play…
A Novel Piecewise Atmospheric Attenuation Model for Free Space Optical Links in Vertical Heterogeneous Networks
Eylem Erdogan, Mohammed Elamassie, Ibrahim Altunbas +3
Free-space optical (FSO) communication is emerging as a key backhaul technology for next-generation vertical heterogeneous networks (VHetNets), whose architecture spans satellites,…
Path-Based Quantum Meta-Learning for Adaptive Optimization of Reconfigurable Intelligent Surfaces
Noha Hassan, Xavier Fernando, Halim Yanikomeroglu
Reconfigurable intelligent surfaces (RISs) modify signal reflections to enhance wireless communication capabilities. Classical RIS phase optimization is highly non convex and chall…
A Novel 3D Antenna Architecture with Spatial Resource Allocation for Massive MIMO HAPS
Rozita Shafie, Omid Abbasi, Halim Yanikomeroglu +1
Spatial correlation poses a significant challenge in massive multiple-input multiple-output (MIMO) high-altitude platform station (HAPS) systems. The inherent spatial correlation a…
Quantum Graph Neural Networks for Double-Sided Reconfigurable Intelligent Surface Optimization
Noha Hassan, Xavier Fernando, Halim Yanikomeroglu
As a key enabler for sixth-generation (6G) wireless communications, reconfigurable intelligent surfaces (RISs) provide the flexibility to control signal strength. Nevertheless, opt…
