Performance evaluation of channel aggregation strategies in cognitive radio networks with queues
2012
Masteroppgave i informasjons- og kommunikasjonsteknologi IKT590 2012 – Universitetet i Agder, Grimstad With the growing usage of wireless communication devices, demand for the spectrum access is rapidly increasing. Therefore, an efficient spectrum management and spectrum access techniques are necessary and critical. However, studies on spectrum usage have revealed that most of the allotted spectrum is not used efficiently due to the static frequency allocation methods. With the evolution of cognitive radio, spectrum access techniques shift from static spectrum allocation to dynamic allocation with enhanced features such as spectrum sensing and spectrum adaptation. In the first part of this …
