Sensing-Spectrum Utilization Tradeoff for Cognitive Radio Sensors

Sensing-throughput tradeoff has already been studied a lot in the theory of cognitive radio sensors. Here, we re-examine this problem of optimizing the sensing duration from a different perspective of maximizing the spectrum utilization. By spectrum utilization, we mean the usage of spectrum either by Primary User (PU) or Secondary User (SU) for successful data transmission. Optimal sensing time is obtained for maximizing the overall spectrum utilization.
