Abstract


Since the emergence of the aeronautical Ad hoc Networks, it can provide effectivecommunication guarantee for the plane across transoccanic flight, and make the planeaccess Internet through the satellite or ground stations to let passengers enjoy the networkresources. However the cost of satellite is expensive, in order to save the cost, we hope touse the ground stations as far as possible to finish the communication. Therefore thispaper is put forward. In the aeronautical Ad hoc Networks, the backbone networks wereformed by the planes which didn’t access the ground stations directly. Under the premiseof not affecting themselves’ usage and sacrificing the certain QoS, the idle spectrum ofthe will leases to other backbone networks or a single plane that urgently need spectrum,which increases the their income and improves the efficiency of spectrum usage. At thesame time, secondary users accessing the backbone networks could access the allocatedspectrum by opportunity which meets the communication need of their bussiness andimproves the whole spectrum usage efficiency.When the scene has multiple primary users and multiple secondary users in theaeronautical Ad hoc Networks, and to meet the needs of matching multiple channels, amodified multi-unit double auction (MDA) mechanism for channel allocation is presented.The mechanism combines and improves the VCG double auction and traditional MDA,and the property of the presented double auction mechanism is discussed. And we provethe presented double auction mechanism satisfies incentive compatibility, budget balance,and individual rationality. Finally, the efficiency of the presented double auctionmechanism is analyzed through experiments, and experimental results show that auctionmechanism is efficient and appropriate for the channel allocation of the TransoccanicAeronautical Ad hoc Networks.Furthermore, considering the selfish users’ collusion, the mobility of planes and thedynamic characteristics of channel, through setting the reserve prices of primary users andsecondary users, then this paper will introduce the double auction model with belieffunction into spectrum allocation, and finally we put forward a dynamic channelallocation model based on continuous double auction. In this model, the primary usersand secondary users build on their belief functions based on the historical information.Combined with their cost and expected profit, and to maximize their gains, they get thecurrent bid/ask price and the optimal reserve price. Comparing the total utilities of competitive equilibrium and the proposed scheme, the simulation results show that theproposed scheme achieves high efficiency of spectrum usage even with the presence ofsevere user collusion. And the total utilities are close to the competitive equilibrium,almost100%as the number of users increasing.
