  Abstract

This paper proposes a cooperative spectrum sensing algorithm in a maritime cognitive radio network and evaluates the performance of proposed algorithm. In the proposed algorithm, the secondary ships decide whether to transmit the feedback information or not on the basis of the threshold when the number of available feedback information of the ships is limited. The fusion ship detects whether the channel is available or not on the basis of the feedback information. This paper evaluates the proposed algorithm in terms of the detection probability and the number of secondary ships that are fed back in the maritime cognitive radio network. The simulation results show the proposed algorithm significantly reduces the feedback overhead even though the detection probability is somewhat declined.
