【摘要】：提出了一種延時拒絕模型下的異構無線網(wǎng)絡接入選擇算法(AS-DRM).通過引入緩沖存儲器,允許彈性業(yè)務進入緩存器隊列中排隊等候,當有閑置資源時按照隊列中的順序依次獲得服務.利用排隊論建立了異構網(wǎng)絡接入資源占用五維馬爾可夫排隊模型,并分析和評價系統(tǒng)性能.仿真結果表明,所提算法能明顯降低彈性業(yè)務阻塞率,提高系統(tǒng)性能.
[Abstract]:An access selection algorithm for heterogeneous wireless networks based on delay rejection model is proposed.By introducing buffer memory, flexible services are allowed to queue in the buffer queue, and service is obtained in order of queue when there are idle resources.Based on the queuing theory, a five-dimensional Markov queuing model for heterogeneous network access resources is established, and the performance of the system is analyzed and evaluated.Simulation results show that the proposed algorithm can significantly reduce the resilient traffic blocking rate and improve the system performance.
