On the Robustness of AoA as an Authentication Feature Under Spoofing: Fundamental Limits from Misspecified Cramer Rao Theory
Sotiris Skaperas, Arsenia Chorti
The robustness of angle of arrival (AoA) as a physical layer authentication (PLA) feature under spoofing attacks is studied, assuming a digital uniform linear array verifier. The v…
Misspecified Crame-Rao Bound for AoA Estimation at a ULA under a Spoofing Attack
Sotiris Skaperas, Arsenia Chorti
A framework is presented for analyzing the impact of active attacks to location-based physical layer authentication (PLA) using the machinery of misspecified Cramér--Rao bound (MCR…
Scheduling Optimization of Heterogeneous Services by Resolving Conflicts
Sotiris Skaperas, Nasim Ferdosian, Arsenia Chorti +1
Fifth generation (5G) new radio introduced flexible numerology to provide the necessary flexibility for accommodating heterogeneous services. However, optimizing the scheduling of…
Real-Time Video Content Popularity Detection Based on Mean Change Point Analysis
Sotiris Skaperas, Lefteris Mamatas, Arsenia Chorti
Video content is responsible for more than 70% of the global IP traffic. Consequently, it is important for content delivery infrastructures to rapidly detect and respond to changes…
