Abstract

Most of the communication in today’s world is shifting toward wireless because of various benefits associated with it. However, these benefits are realized at the expense of extensive research done in this field to improve the efficiency of spectrum utilization. This necessitated the evolution of a new technique referred to as dynamic spectrum access and cognitive radio networks. An unending research in this field has made it a topic of interest in today’s era. This paper is also an attempt toward understanding the basic model of a cognitive radio. Formulation of a simple channel allocation algorithm and its queuing-based improvement form the core of this paper. Finally, an extensive quantitative analysis of the results provides a better understanding of the model and the scope for future improvements. The result for an optimum environment shows that the proposed queuing-based improvement outperforms simple allocation by a relative increase in channel usage around 19% (1 over 0.84) and secondary usage, around 47% (0.34 over 0.23).
