Collision Avoidance in TV White Spaces: A Cross-layer Design Approach for Cognitive Radio Networks
Fotis Foukalas, George Karetsos
One of the most promising applications of cognitive radio networks (CRNs)is the efficient exploitation of TV white spaces (TVWSs) for enhancing the performance of wireless networks…
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…
