跨洋航空网络的频谱共享博弈模型

提出一种跨洋航空网络中主干网络的频谱共享博弈模型。该模型综合考虑了主用户和所有次级用户的收益,主用户可在保证自身收益最大的前提下对各次级用户进行有效的频谱分配;各次级用户根据主用户的最佳单位定价改变请求带宽以获得最大收益。给出了该模型的静态博弈纳什均衡与动态博弈收敛结果,通过与次级用户收益的最优化模型进行比较,验证了用该模型解决跨洋航空网络中主干网络上的频谱分配问题具有公平性。

Spectrum sharing game model in transoceanic aeronautic networks

A spectrum sharing game model in core network of transoceanic aeronautic networks is proposed.The model considers gain of both the primary user and all secondary users.Primary user can allocate the spectrum effectively to the secondary users under their largest profit.Secondary users will change request bandwidth to gain maximum profits according to the primary user’s best unit pricing.The static game Nash equilibrium and dynamic game convergence results is presented.Comparing with the optimizing model,the model is proved to solve the spectrum sharing problem well in the transoceanic aeronautic networks,thus verify the fairness of the Nash equilibrium.
