摘要:
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.
Abstract:
For providing mobile Internet access requirements by the integration of IEEE 802.16 and IEEE 802.11 standards, we design heterogeneous wireless network integration model using WiMAX as Wi-Fi backhaul support. Using OPNET simulation tool for the modeling, based on the network self-similar traffic model Pareto distribution to generate network 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 performance 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 requirements of the heterogeneous wireless network VoIP, HTTP and FTP applications such as QoS(quality of service).
