User cooperation for spectrum sensing in cognitive radios has been proposed in order to improve the overall performance by mitigating multi-path fading and shadowing experienced by the users. However, user cooperation results in high energy consumption, extra time for results exchange, as well as delay and security risks. In this paper, we investigate the effects of cooperative spectrum sensing (CSS) on energy consumption and achievable performance. Our analysis is based on a limited time… CONTINUE READING
