An innovative paradigm namedCooperativeCognitiveMaritimeCyber Physical Systems (CCMCPSs) is developed to achieve highspeed\nand low-cost communication services. The analysis of the available white space at sea, as well as the framework, is presented.\nSpecifically, a bilevel game with two stages of PUs-to-SUs (primary users to secondary users) and SUs-to-SUs is proposed, to address\nthe resource allocation issue of Decode-and-Forward (DF) relay mode with maximal-ratio combining (MRC) receiving mode in\ndestination. Stackelberg game with priority is employed between PU and SUs, while a symmetrical system model is considered\namong SUs-to-SUs.The game theoretic procedure that converges to Nash equilibrium based on the utility and payoff function is\nillustrated. Simulation results demonstrate that our proposed strategy could effectively increase the throughput ascwell as the payoffs\nof the system.
