In recent years, several algorithms for controlling cognitive radio platforms have been
proposed. In this paper, we review the existing approaches that have been developed for …

This paper presents an architecture for adaptive cognitive radio networks based on the
concept of a" global control plane". The proposed control architecture uses a predetermined …

The concept of cognitive radio networks has introduced a new way of sharing the open
spectrum flexibly and efficiently. However, there are several issues that hinder the …

In recent years, various types of control algorithms have been proposed for cognitive radios
(CR), ranging from algorithms coordinated by centralized control to ones coordinated in a …

In this paper, a cognitive radio network (CRN) model is presented. In this model, the control
