Cross-layer Design of CSMA/CA with Spectrum Sensing for Cognitive Radio Networks
F. Foukalas, G. T. Karetsos, P. Chatzimisios
We devise a cross-layer design (CLD) of carrier sensing multiple access with collision avoidance (CSMA/CA) at the medium access control (MAC) layer with spectrum sensing (SpSe) at…

On the Performance of Adaptive Modulation in Cognitive Radio Networks
F. Foukalas, G. T. Karetsos
We study the performance of cognitive radio networks (CRNs) when incorporating adaptive modulation at the physical layer. Three types of CRNs are considered, namely opportunistic s…

Capacity Optimization through Sensing Threshold Adaptation for Cognitive Radio Networks
Fotis Foukalas, George T. Karetsos, Lazaros Merakos
In this paper we propose the capacity optimization over sensing threshold for sensing-based cognitive radio networks. The objective function of the proposed optimization is to maxi…
