基于Stackelberg博弈的网络虚拟化资源分配方法

A Stackelberg game-based resource allocation algorithm for network virtualization

在网络虚拟化环境中,基于Stackelberg博弈模型提出了静态博弈算法下网络运营商对频谱的定价策略及静态和动态博弈算法下各虚拟运营商的频谱分配方法,并推导了各运营商收益最大时的纳什均衡点。该方法能同时满足网络运营商和虚拟网络运营商收益最大化的需求。仿真结果验证了算法的有效性及纳什均衡点的存在性。

In a network virtualization environment,the pricing strategy of network operators for spectrum allocation using the static game algorithm and the spectrum allocation method of every virtual operator using the static and dynamic game algo-rithms are proposed on the basis of a Stackelberg game model.In addition,the Nash equilibrium point when the profit of each operator is the maximum is derived.This method can maximize the revenues of network operators and virtual network opera-tors simultaneously.Simulation results verify the effectiveness of the algorithm and the existence of Nash equilibrium point.
