| Summary: | Cognitive radio is regarded as one of the
transformational technologies that play a fundamental role in
establishment and development of next generation wireless
networks. Clustering based cognitive radio networks can reduce
the energy consumption and increase the spectrum sensing
accuracy. In this paper, we investigate the performance of a
cognitive radio network with a clustering architecture for
cooperative spectrum sensing. The network efficiency is
evaluated in terms of throughput and energy consumption, under
fading channel conditions. Simulation results show significant
improvement of energy efficiency compared to the conventional
non-clustering method by ensuring allowable interference with
primary users. |
