Dual-Graph Multi-Agent Reinforcement Learning for Handover Optimization
Matteo Salvatori, Filippo Vannella, Sebastian Macaluso +5
HandOver (HO) control in cellular networks is governed by a set of HO control parameters that are traditionally configured through rule-based heuristics. A key parameter for HO opt…
SORIS: A Self-Organized Reconfigurable Intelligent Surface Architecture for Wireless Communications
Evangelos Koutsonas, Alexandros-Apostolos A. Boulogeorgos, Stylianos E. Trevlakis +3
In this paper, a new reconfigurable intelligent surface (RIS) hardware architecture, called self-organized RIS (SORIS), is proposed. The architecture incorporates a microcontroller…
Markov Chain-based Model of Blockchain Radio Access Networks
Vasileios Kouvakis, Stylianos E. Trevlakis, Alexandros-Apostolos A. Boulogeorgos +3
Security has always been a priority, for researchers, service providers and network operators when it comes to radio access networks (RAN). One wireless access approach that has ca…
Simultaneous Information and Control Signalling Protocol for RIS-Empowered Wireless Systems
Evangelos Koutsonas, Xiaonan Mu, Nan Qi +3
Integration of RIS in radio access networks requires signaling between edge units and the RIS microcontroller (MC). Unfortunately, in several practical scenarios, the signaling lat…
Spiking Neural Networks for Resource Allocation in UAV-Enabled Wireless Networks
Vasileios Kouvakis, Stylianos E. Trevlakis, Ioannis Arapakis +1
This work presents a new spiking neural network (SNN)-based approach for user equipment-base station (UE-BS) association in non-terrestrial networks (NTNs). With the introduction o…
High-Fidelity Coherent-One-Way QKD Simulation Framework for 6G Networks: Bridging Theory and Reality
Aitor Brazaola-Vicario, Vasileios Kouvakis, Stylianos E. Trevlakis +4
Quantum key distribution (QKD) has been emerged as a promising solution for guaranteeing information-theoretic security. Inspired by this, a great amount of research effort has bee…
