Research On Resource Allocation Towards To Secure Communications For Maritime CPSs

Development and utilization of maritime resources on the coastal areas,which has great significance for the social development and entire country’s economic.Compared with the ever-changing changes from 1G to 5G on land,maritime communication has lagged far behind land communications due to environmental and construction difficulties.With the rapid development of maritime activities in China and the rapid development of marine economy,it is urgent to explore the development of a new marine communication network with high speed,high reliability,full coverage,easy management,flexibility and low cost.An innovative paradigm named Cooperative Cognitive Maritime Cyber Physical Systems(CCMCPSs)is developed to achieve high speed and low-cost communication services.The analysis of the available white space at sea is proposed as well as the framework.Specifically,a bilevel game with two stages of PUs-to-SUs(primary users to secondary users)and SUs-to-SUs are proposed,to solve the resource allocation issue of Decode-and-Forward(DF)relay mode with maximal-ratio combining(MRC)receiving mode in destination.Stackelberg game with priority is employed between PU and SUs,while a symmetrical system model is considered among SUs-to-SUs.And then,an innovative framework labeled as CCMCPSs on the sea is developed to provide opportunistic channel access and secure communication.Power consumption and time portion for secure communication scenario are considered.Specifically,a jammer-based secure communications scheme is developed to maximize the secure utility of PU.Close-form solutions for the best access time portion as well as the power for SU and jammer are derived to realize the Nash Equilibrium based on Stackelberg game.Simulation results validate the effectiveness of our proposed strategy.
