Analysis and Design of a Reconfigurable Metasurface based on Chalcogenide Phase-Change Material for Operation in the Near and Mid Infrared
Alexandros Pitilakis, Alexandros Katsios, Alexandros-Apostolos A. Boulogeorgos
We analyze, design and assess the performance of a reflective reconfigurable metasurface (MS) architecture for optical wireless communications. The device is based on the Ge-Sb-Te…
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…

This article introduces a comprehensive metaverse framework, which is designed for the simulation, emulation, and interaction with wireless systems. The proposed framework integrat…
Dual-UAV-Aided Covert Communications for Air-to-Ground ISAC Networks
Jingke Sun, Liang Yang, Alexandros-Apostolos A. Boulogeorgos +2
To enhance both the sensing and covert communication performance, a dual-unmanned aerial vehicle (UAV)-aided scheme is proposed for integrated sensing and communication networks, i…
Fairness vs. Equality: RSMA-Based Multi-Target and Multi-User Integrated Sensing and Communications
Xudong Li, Rugui Yao, Alexandros-Apostolos A. Boulogeorgos +1
This paper investigates the tradeoff between sensing and communication in an ISAC system comprising multiple sensing targets and communication users. A dual-functional base station…
Covert Communications in Active-IOS Aided Uplink NOMA Systems With Full-Duplex Receiver
Xueyu Kang, Nan Qi, Lu Lv +3
In this paper, an active intelligent omni-surface (A-IOS) is deployed to aid uplink transmissions in a non-orthogonal multiple access (NOMA) system. In order to shelter the covert…
Secure and Green RSMA-Assisted Heterogeneous ISAC
Xudong Li, Rugui Yao, Theodoros A. Tsiftsis +1
This paper investigates sensing, communication, security, and energy efficiency of the heterogeneous integrated sensing and communication networks under challenging operational con…
