Abstract
With the ever-growing demand for technological advancement in the field of wireless communication to accommodate the huge increase in users, research on cognitive radio has been flourishing. Apart from develo** ways to utilize the underused portions of the spectrum, it is equally important to explore the unused portion to expand its utility. In this paper, a technique for channel assignment is proposed which takes the available data rates of the vacant channels as well as the data rate required by the secondary users. For the purpose of comparing the effectiveness of the proposed method, simulation of this process is carried out in comparison with the sequential method. The number of secondary users served for a range of busy probabilities is found out and the obtained results are used to plot a graph which can be used to determine how the variable data rate assignment method utilizes the available channels better than the existing sequential method.
