Reliable ORIS-assisted FSO Communications via HARQ
Georgios D. Chondrogiannis, Athanasios P. Chrysologou, Vasilis K. Papanikolaou +3
This paper studies a free-space optical (FSO) link assisted by an optical reconfigurable intelligent surface (ORIS) and enhanced by a hybrid automatic repeat request (HARQ) scheme.…
Parametrization of microbial survival models under UVC exposure
Aikaterini A. Tsantari, Konstantinos K. Delibasis, Harilaos G. Sandalidis +1
This work presents a unified framework for the parametrization and comparison of microbial survival models under UVC exposure. Four dose-response models - the single-target, multi-…
Optical RIS-enabled Multiple Access Communications
Georgios D. Chondrogiannis, Athanasios P. Chrysologou, Alexandros-Apostolos A. Boulogeorgos +2
In this paper, we identify optical reconfigurable intelligent surfaces (ORISs) as key enablers of next-generation free-space optical (FSO) multiple access systems. By leveraging th…
On the Reliability and Security of Ambient Backscatter Uplink NOMA Networks
Athanasios P. Chrysologou, Nestor D. Chatzidiamantis, Alexandros-Apostolos A. Boulogeorgos +1
A fundamental objective of the forthcoming sixth-generation wireless networks is to concurrently serve a vast array of devices many of which, such as Internet-of-Things (IoT) senso…
Power-Optimal HARQ Protocol for Reliable Free Space Optical Communication
Georgios D. Chondrogiannis, Nikos A. Mitsiou, Nestor D. Chatzidiamantis +2
This paper investigates the usage of hybrid automatic repeat request (HARQ) protocols for power-efficient and reliable communications over free space optical (FSO) links. By exploi…
Mixed RF-VLC Relaying Systems for Interference-Sensitive Mobile Applications
Milica I. Petkovic, Aleksandra M. Cvetkovic, Milan Narandzic +3
Due to their Radio-Frequency (RF) immunity, Visible Light Communications (VLC) pose as a promising technology for interference sensitive applications such as medical data networks.…
