Paper Title - An Efficient Spectrum Decision Making Framework For Cognitive Radio Networks


Abstract
This review paper is based on the spectrum decision framework for cognitive radio networks. Cognitive radio networks have been proposed as a solution to both spectrum inefficiency and spectrum scarcity problems. However, they face to a unique challenge based on the fluctuating nature of heterogeneous spectrum bands as well as the diverse service requirements of various applications. In this paper, a spectrum decision framework is proposed to determine a set of spectrum bands by considering the application requirements as well as the dynamic nature of spectrum bands. To this end, first, each spectrum is characterized by jointly considering primary user activity and spectrum sensing operations. Based on this, a minimum variance based spectrum decision is proposed for real-time applications, which minimizes the capacity variance of the decided spectrum bands subject to the capacity constraints. For best-effort applications, a maximum capacity- based spectrum decision is proposed where spectrum bands are decided to maximize the total network capacity. Keywords- Cognitive Radio Requirements, Dynamic Spectrum Access, Spectrum Sensing, Spectrum Allocation, Spectrum Decision Framework.
