Abstract
Cognitive radio is a key technology to overcome spectrum scarcity by using spectrum opportunistically. It can be applied to maritime wireless networks to provide more bandwidth and reduce communication cost. Spectrum sensing is a primary issue to develop cognitive radio networks. There are few challenges for spectrum sensing in maritime networks which are different from terrestrial networks, for example, sea’s surface channel properties. High probability of detection is required to achieve better network performance. In this paper, centralized cooperative spectrum sensing schemes are compared for maritime cognitive radio networks. The simulation results show that exiting schemes are well suitable for lower sea states but fail for higher sea states and we need to devise some advanced algorithms for spectrum sensing in the maritime wireless networks.
