Abstract
Cognitive radio (CR) is an emerging technology that helps efficiently use spectrum. In this paper, a collaborative spectrum sensing mechanism is proposed which combines passive detection and sensing service compensation. Theoretical analysis and simulations show that this method not only reduces the energy cost and the passive sensing time, but also maintains fairness in the CR communication systems.
Keywords: Cognitive radio, Collaborative spectrum sensing, Detection time, Sensing mechanism.
