A Spectrum Decision Framework for Real Time and Best Effort Applications in Cognitive Radio Networks
نویسنده
چکیده
RF spectrum is a scarce resource. It is inefficient when no of users are increased. So cognitive radio is developed for provide to efficient use of bandwidth utilization. Licensed users are primary users and unlicensed users are secondary users. Cognitive radio enables the secondary usage of unused licensed spectrum band. In this Paper, we propose spectrum decision framework for best effort application and real time applications in cognitive radio networks. Spectrum decision framework for real time applications, it minimizes the capacity variance of decided selected band. For best effort applications, spectrum decision framework decides the spectrum band to maximize the total network capacity.
