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…
Can graph neural network-based detection mitigate the impact of hardware imperfections?
Lamprini Mitsiou, Stylianos Trevlakis, Argiris Tsiolas +3
Until recently, researchers used machine learning methods to compensate for hardware imperfections at the symbol level, indicating that optimum radio-frequency transceiver performa…
From NEA and NIA to NESAS and SCAS: Demystifying the 5G Security Ecosystem
Angelos Michalas, Constantinos Patsakis, Dimitrios D. Vergados +1
Despite the numerous pompous statements regarding 5G, it is indisputable that 5G creates a radical shift in telecommunications. The main reason is that 5G is an enabler of numerous…
Performance of Uplink NOMA with User Mobility Under Short Packet Transmission
Nikolaos I. Miridakis, Emmanouel T. Michailidis, Angelos Michalas +3
The scenario of an uplink two-user non-orthogonal multiple access (NOMA) communication system is analytically studied when it operates in the short packet transmission regime. The…
Energy Optimization in Massive MIMO UAV-Aided MEC-Enabled Vehicular Networks
Emmanouel T. Michailidis, Nikolaos I. Miridakis, Angelos Michalas +3
This paper presents a novel unmanned aerial vehicle (UAV) aided mobile edge computing (MEC) architecture for vehicular networks. It is considered that the vehicles should complete…
Local Voting: A New Distributed Bandwidth Reservation Algorithm for 6TiSCH Networks
Dimitrios J. Vergados, Katina Kralevska, Yuming Jiang +1
The IETF 6TiSCH working group fosters the adaptation of IPv6-based protocols into Internet of Things by introducing the 6TiSCH Operation Sublayer (6top). The 6TiSCH architecture in…
