Survey on QoS Provisioning Techniques for Cognitive Radio Networks
Hui Zhang · Journal of Nanjing University of Posts and Telecommunications · 2010
The basic ideas of Dynamic Spectrum Access(DSA) and Cognitive Radio(CR) are introduced,and the challenges of provisioning QoS in CR networks based on DSA are analyzed.Systematic introduction of the state-of-the-art and problems is provided towards the QoS provisioning techniques in CR key techniques(spectrum sensing,spectrum management,spectrum mobility and spectrum sharing) and upper layers techniques as well as cross-layer design techniques.Finally,problems and research directions of these QoS provisioning techniques are given.
