提出了一种延时拒绝模型下的异构无线网络接入选择算法(AS-DRM).通过引入缓冲存储器,允许弹性业务进入缓存器队列中排队等候,当有闲置资源时按照队列中的顺序依次获得服务.利用排队论建立了异构网络接入资源占用五维马尔可夫排队模型,并分析和评价系统性能.仿真结果表明,所提算法能明显降低弹性业务阻塞率,提高系统性能.
(AS-DRM) is proposed in this paper, which is based on the delay denial model.It introduces the buffer memory to allow the elastic service to queue in the buffer queue and wait for it when there are idle resources, And then get the service.Using queuing theory to establish heterogeneous network access resources occupy five-dimensional Markov queuing model and analyze and evaluate the system performance.The simulation results show that the proposed algorithm can significantly reduce the blocking rate of flexible services and improve system performance.
