Notification-based cooperative spectrum sensing for ship ad-hoc network

Via the cognitive radio (CR) technology, the ship ad-hoc network (SANET) can effectively utilize the system spectrum. To reduce the interference brought into the primary network, the hidden primary user problem should be carefully considered for the SANET applications. In this paper, we suggest a notification-based cooperative spectrum sensing scheme used to solve such a problem. The numerical results illustrate that the proposed scheme is reliable to detect the primary user by reducing the missing probability.
