摘　　要：针对传统无线网络中功率不能动态分配共享的问题,采用无线网络虚拟化,设计了一种基于博弈的两阶段功率分配方法(G2SPA,game theory based two steps power allocation scheme for wireless network virtualization),首先利用买卖博弈模拟了服务提供商(SP,service provide)和移动用户(MUE,mobile user equipment)之间的相互影响,提出了基于斯坦博格均衡(SE,stackelberg equilibrium)的报价策略。然后,利用拍卖理论对空闲下行功率资源进行再分配,采取Mc Afee机制保证拍卖的诚实性。通过仿真实验证明G2SPA算法的正确性和有效性。In traditional wireless network, resource couldn＇t be efficiently and flexibly. To this end, wireless network vir- tualization was used to manage and share resource. A game theory based two steps power allocation scheme for wireless network virtualization, called G2SPA, was proposed, which designed a stackelberg equilibrium （SE） price strategy based on the interactions between SP and mobile user equipment （MUE）, and then MacAfee based auction to reallocate leisure resource was performed. The numerous experimental simulation results show that the rightness and effectiveness of G2SPA.
