Distance Distributions Between Nodes in Concentric Disk-Annulus or Sphere-Shell Regions
Nicholas Vaiopoulos, Alexander Vavoulas, Harilaos G. Sandalidis +1
This letter derives closed-form expressions for the probability density function of the distance between two nodes located in heterogeneous concentric geometries, namely a disk or…
Internodal Distance Distributions for Static and Mobile Nodes in 2D/3D Wireless Networks
Nicholas Vaiopoulos, Alexander Vavoulas, Harilaos G. Sandalidis +2
This letter presents a unified analytical framework for internodal distance distributions in 2D and 3D wireless networks, with nodes confined to concentric circular or spherical re…
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-…
Efficient UAV Coverage in Large Convex Quadrilateral Areas with Elliptical Footprints
Alexander Vavoulas, Konstantinos K. Delibasis, Harilaos G. Sandalidis +2
Unmanned Aerial Vehicles (UAVs) have gained significant attention for improving wireless communication, especially in emergencies or as a complement to existing cellular infrastruc…
Optimizing Coverage in Convex Quadrilateral Regions with a Single UAV
Alexander Vavoulas, Nicholas Vaiopoulos, Konstantinos K. Delibasis +1
The integration of unmanned aerial vehicles (UAVs) into next-generation wireless networks has emerged as a promising solution for providing flexible and efficient coverage. This pa…
On the Terminal Location Uncertainty in Elliptical Footprints: Application in Air-to-Ground Links
Alexander Vavoulas, Nicholas Vaiopoulos, Harilaos G. Sandalidis +1
Wireless transmitters (Txs) that radiate downward in a direction often generate circular footprints on the ground. The configurational flexibility of these footprints is inherently…
Performance Analysis of Multi-Reconfigurable Intelligent Surface-Empowered THz Wireless Systems
Alexandros-Apostolos A. Boulogeorgos, Nestor Chatzidiamantis, Harilaos G. Sandalidis +2
In this paper, we introduce a theoretical framework for analyzing the performance of multi-reconfigurable intelligence surface (RIS) empowered terahertz (THz) wireless systems subj…
Cascaded Composite Turbulence and Misalignment: Statistical Characterization and Applications to Reconfigurable Intelligent Surface-Empowered Wireless Systems
Alexandros-Apostolos A. Boulogeorgos, Nestor Chatzidiamantis, Harilaos G. Sandalidis +2
Reconfigurable intelligent surfaces (RISs) empowered high-frequency (HF) wireless systems are expected to become the supporting pillar for several reliability and data rate hungry…
