无线局域网（WLAN）在设计用于使驾驶更安全的车内联网系统中越来越受欢迎。无线网状网络（WMN）被广泛部署以扩大高速WLAN的覆盖范围并以低成本支持移动的用户随时随地的最后一英里连接。最近的许多测量研究表明，无线网络中的业务到达过程表现出突发性和相关性。本文开发了一种新的分析模型，作为一个具有成本效益的性能工具，调查的服务质量（QoS）的无线网状网，在存在突发性和相关的流量互连多个无线局域网。通过大量的仿真实验验证其准确性后，分析模型，然后用于调查的混合无线网络的性能。
Wireless local area networks (WLANs) have risen in popularity for in-car networking systems that are designed to make driving safer. Wireless mesh networks (WMNs) are widely deployed to expand the coverage of high-speed WLANs and to support last-mile connectivity for mobile users anytime and anywhere at low cost. Many recent measurement studies have shown that the traffic arrival process in wireless networks exhibits the bursty and correlated nature. A new analytical model is developed in this paper as a cost-effective performance tool to investigate the quality-of-service (QoS) of the WMN that interconnects multiple WLANs in the presence of bursty and correlated traffic. After validating its accuracy via extensive simulation experiments, the analytical model is then used to investigate the performance of the hybrid wireless networks.
