摘　　要：对异构无线网络环境中高效合理分配网络资源面临的均衡用户接入与网络选择的问题进行分析,提出一种支持单/多宿主用户共存的基于非合作博弈的异构无线网络资源分配算法。该算法设计了一种考虑合理分配网络带宽的非合作博弈模型,并证明了纳什均衡的存在性。为了实现网络间效用的最大化,在非合作博弈模型的基础上,通过适合异构网络环境下单/多宿主用户共存的资源分配算法实现网络资源的统筹合理分配。仿真实验表明,所提网络资源分配算法在网络接入阻塞率、网络负载平衡和资源利用率等指标上均表现出较好的性能。By analyzing the problem of balancing user access and network selection for efficient and reasonable allocation of network resources in heterogeneous wireless network environment,a non-cooperative game based resource allocation algorithm for heterogeneous wireless networks is proposed,which supports the coexistence of single/multi host users.The non-cooperative game model considering reasonable network bandwidth allocation is designed and then the existence of Nash equilibrium is proved.In order to maximize the utility between networks,based on the non-cooperative game model,the resource allocation algorithm suitable for the coexistent of single/multiple hosts users in heterogeneous network is used to allocate network resources reasonably.Simulation results show that the proposed algorithm has good performance in access blocking rate,load balancing and resource utilization.
