  • Abstract
    Compared with traditional communication systems, cognitive radio (CR) systems consume additional sensing and reporting energy. Minimising additional energy consumption while maintaining maximum throughput is an emerging issue in CR systems. Proposed is a discontinuous spectrum sensing scheme for CR systems that adopts cooperative spectrum sensing. The simulation results show that the proposed scheme can achieve remarkable energy savings with negligible throughput loss.
