摘　　要：提出一种低复杂度的分层匹配博弈结合比例公平的无线虚拟网络资源分配策略。策略采用两层独立的匹配博弈避免两层循环导致的较高计算复杂度,博弈下层为用户(Users,UEs)与移动虚拟网络操作层(Mobile Virtual Network Operators,MVNOs)构成的多对一匹配,实现UEs对MVNOs的依偏好选择,上层为基础设施提供层(Infrastructure Providers,InPs)与MVNOs构成的多对一匹配,实现MVNOs对切片依偏好选择,从而实现用户组与切片组效用最高匹配。然后,在匹配的用户组与切片组间采用功率受限的比例公平资源分配策略,实现用户与切片的精确匹配,并在比例公平条件下使频谱效率最大。仿真表明,该策略虽然比两层联合的匹配博弈效用略低,但降低了计算复杂度,提高了频谱效率,总体性能更优。A low-complexity resource allocation strategy using hierarchical matching game approach combined with proportional fair principle for wireless virtual network is proposed in this paper.Two layers of independent matching games is addressed to realize the matching of user groups and slice groups in it,avoiding the high computational complexity caused by two-layer circulation.The lower layer is the Many-to-one matching between users(UEs)and Mobile Virtual Network Operators(MVNOs)to achieve UEs’selection of MVNOs on preference profiles.And the upper layer is the Many-to-one matching between the Infrastructure Providers(InPs)and MVNOs to achieve the selection of slices by MVNOs,also on preference profiles,so as to match the user groups and slice groups on efficiency.Then a power-constrained proportional fair resource allocation strategy is used between slices and MVNOs to achieve accurate matching between users and slices,and maximize system efficiency while ensuring proportional fairness.Simulation results show that the schemes proposed in this paper reduces the computational complexity,improves the spectral efficiency,and provides a better overall performance,in spite of the small drops of utility compared with the traditional hierarchical matching game.
