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…
On the physical layer security capabilities of reconfigurable intelligent surface empowered wireless systems
Alexandros--Apostolos A. Boulogeorgos, Angeliki Alexiou, Angelos Michalas
In this paper, we investigate the physical layer security capabilities of reconfigurable intelligent surface (RIS) empowered wireless systems. In more detail, we consider a general…
Perpetual Reconfigurable Intelligent Surfaces Through In-Band Energy Harvesting: Architectures, Protocols, and Challenges
Konstantinos Ntontin, Alexandros-Apostolos A. Boulogeorgos, Sergi Abadal +3
Reconfigurable intelligent surfaces (RISs) are considered to be a key enabler of highly energy-efficient 6G and beyond networks. This property arises from the absence of power ampl…
Toward Autonomous Reconfigurable Intelligent Surfaces Through Wireless Energy Harvesting
Konstantinos Ntontin, Alexandros-Apostolos A. Boulogeorgos, Emil Björnson +9
In this work, we examine the potential of autonomous operation of a reconfigurable intelligent surface (RIS) using wireless energy harvesting from information signals. To this end,…
