Priority Queuing based Spectrum Sensing Methodology

Radio spectrum is becoming scarce resource due to increase in the usage of wireless ommunication devices. However studies have revealed that most of the allotted spectrum is not used effectively. Given the demand for more bandwidth and the amount of underutilized spectrum, DSA (Dynamic Spectrum Access) networks employing cognitive radios are a solution that can revolutionize the telecommunications industry, significantly changing the way we use spectrum resources, and design wireless systems and services. Cognitive radio has improve the spectral efficiency of licensed radio frequency bands by accessing unused part of the band pportunistically without interfering with a license primary user PU. In this thesis we investigate the effects on the quality of service (QoS) performance of spectrum management techniques for the connection-based channel usage behavior for Secondary user (SU).

I had worked as Field Engineer for Myson Engineering Systems one of leading Sub contractor providing its services to leading cellular companies like Telenor. I had on job training, in which I came to know different parts of Global System of Mobile of Communication or G.S.M. which consist of Radio Network Planning.
