结合 IEEE 802．16和 IEEE 802．11标准实现移动互联网的接入，设计一种将 WiMAX 作为 Wi-Fi 回程支持的异构无线网络融合模型．利用 OPNET 仿真工具进行建模，采用自相似 Pareto 分布生成实时、非实时业务的网络流量，并根据不同应用的优先级需求，得出异构无线网络中相应业务的最优配置．分析结果表明：该融合模型与传统模型相比，不仅在实时和非实时业务上的时延抖动和响应时间更优，而且能满足异构无线网络对 VoIP，HTTP 和 FTP 等应用的服务质量（QoS）需求．

For providing mobile Internet access requirements by the integration of IEEE 802.16 and IEEE 802.11 stand-ards,we design heterogeneous wireless network integration model using WiMAX as Wi-Fi backhaul support.Using OP-NET simulation tool for the modeling,based on the network self-similar traffic model Pareto distribution to generate net-work traffic of real-time and non-real-time services.According to the priority needs of different traffic,we get the optimal configuration of corresponding service in the heterogeneous wireless network.Through of the analysis of network per-formance indicators in the experiment,it is proved that the integration model in comparison with the traditional model of real-time and non-real-time business,not only delay jitter and response time better,but also the model can meet the re-quirements of the heterogeneous wireless network VoIP,HTTP and FTP applications such as QoS (quality of service).
