A Spectrum Decision Framework For Cognitive Radio Networks: Overview

Cognitive radio networks are developed for solutions to spectrum inefficiency problem. In this paper, the authors propose spectrum decision framework that will capable of maintaining data loss rate at lower level and total capacity at higher level. The objective of the spectrum decision framework for real time applications traffic, MVSD (Minimum Variance Based Spectrum Decision) will implement which determines the spectrum bands to minimize the capacity variance i.e. it maintains the data loss rate although the number of users increases and for best effort applications traffic, MCSD (Maximum Capacity based Spectrum Decision) will implement which decides spectrum bands to increase or maximize the total capacity.
