Error analysis of mixed THz0RF wireless systems
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou
In this letter, we introduce a novel mixed terahertz (THz)-radio frequency (RF) wireless system architecture, which can be used for backhaul/fronthaul applications, and we deliver…
Exploiting Statistical and Structural Features for the Detection of Domain Generation Algorithms
Constantinos Patsakis, Fran Casino
Nowadays, malware campaigns have reached a high level of sophistication, thanks to the use of cryptography and covert communication channels over traditional protocols and services…
Chains with Small Intervals in the Lattice of Binary Paths
I. Tasoulas, K. Manes, A. Sapounakis +1
We call an interval in a poset {\em small} if is the join of some elements covering . In this paper, we study the chains of paths from a given arbitrary (binary) pat…
A cooperative localization-aided tracking algorithm for THz wireless systems
Giorgos Stratidakis, Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou
In this paper, a novel cooperation-aided localization and tracking approach, suitable for terahertz (THz) wireless systems is presented. It combines an angle of arrival (AoA) track…
Ergodic capacity evaluation of wireless THz fiber extenders
Evangelos N. Papasotiriou, Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou
This paper focuses on delivering quantified results for the evaluation of the aggregated impact of stochastic antenna misalignment, multipath fading and hardware imperfections on t…
Encrypted and Covert DNS Queries for Botnets: Challenges and Countermeasures
Constantinos Patsakis, Fran Casino, Vasilios Katos
There is a continuous increase in the sophistication that modern malware exercise in order to bypass the deployed security mechanisms. A typical approach to evade the identificatio…
