Recently, cognitive radio (CR) technology has been spotlighted for the efficient use of limited frequency bands. The most important part of CR technology is to protect the incumbent user communications. Therefore, CR device should periodically sense not only the currently using channel, but also some other channels to prepare candidates. In this paper, we propose a cooperative channel sensing mechanism that can effectively protect the primary users and also efficiently save the energy… CONTINUE READING
