Zusammenfassung:In cognitive radio networks, secondary users can opportunistically utilize the unused spectrum holes that are originally licensed to primary users. Therefore, spectrum sensing for seeking unutilized spectrum is a key element to establish cognitive radio network successfully, and cooperative spectrum sensing is a promising way to obtain more trustable sensing results. This paper considers the scenario in which secondary users monitor multiple channels employing cooperative spectrum sensing. Based on the concept of group-based management for spectrum sensing, we propose sensing allocation algorithm in which SUs are allowed to sense the channel which they can monitor reliably. The simulation results show that detection performance is improved in comparison with the conventional scheme.
