Optimizing Access Mechanisms for QoS Provisioning in Hardware Constrained Dynamic Spectrum Access
Spyridon Vassilaras, George C. Alexandropoulos
One of the major challenges in Dynamic Spectrum Access (DSA) systems is to guarantee a required level of Quality of Service (QoS) to secondary users of the spectrum. In this paper,…
Robust measurement-based buffer overflow probability estimators for QoS provisioning and traffic anomaly prediction applicationm
Spyridon Vassilaras, Ioannis Ch. Paschalidis
Suitable estimators for a class of Large Deviation approximations of rare event probabilities based on sample realizations of random processes have been proposed in our earlier wor…
Bit Error Rate Analysis of Cooperative Beamforming for Transmitting Individual Data Streams
Spyridon Vassilaras, George C. Alexandropoulos, Antonis A. Kalis
Cooperative beamforming (CB) has been proposed as a special case of coordinated multi-point techniques in wireless communications. In wireless sensor networks, CB can enable low po…
