In this paper, we consider an optimization of number of secondary users (SUs) in a cooperative spectrum sensing by maximizing the energy efficiency of the cognitive radio network. We obtain the mathematical expressions for number of SUs using OR and AND fusion rules at the fusion center. We consider energy detector as an example for the analysis, based on the analysis we show that performance obtained for OR rule is better than the AND rule.
