Robust Cooperative Spectrum Sensing Scheduling Optimization in Multi-Channel Dynamic Spectrum Access Networks
Chun-Hao Liu, Arash Azarfar, Jean-Francois Frigon +2
Dynamic spectrum access (DSA) enables secondary networks to find and efficiently exploit spectrum opportunities. A key factor to design a DSA network is the spectrum sensing algori…
Delay Analysis of Multichannel Opportunistic Spectrum Access MAC Protocols
Arash Azarfar, Jean-François Frigon, Brunilde Sansò
We provide in this paper a comprehensive delay and queueing analysis for two baseline medium access control (MAC) protocols for multi-user cognitive radio (CR) networks and investi…
Priority Queueing Models for Cognitive Radio Networks with Traffic Differentiation
Arash Azarfar, Jean-François Frigon, Brunilde Sansò
In this paper, we present a new queueing model providing the accurate average system time for packets transmitted over a cognitive radio (CR) link for multiple traffic classes with…
