无线网状网的研究与探讨无线网状网的研究与探讨 ? 摘要：无线网状网由网格路由器和网格客户端组成，其中网状路由器具有最小可移动性，形成了无线网状网的骨干，它们同时为网状客户端和普通客户端提供网络访问。通过网状路由器的网关和桥接的功能，无线网状网能同其它的无线网比如Internet,蜂窝网，无线局域网，传感网络等互联。无线网状网被期望用来解决ad hoc网络，无线局域网及无线城域网的局限性和大量的提高它们的效率，这些网络经历了快速的进步同时产生了大量的配置。无线网状网将承载本地网，校园网和城域网大量不同应用的无线服务。尽管近期无线网状网有了快速进步，但许多研究始终面临着各协议层的挑战。本文将呈现给大家有关无线网状网的细节学习和研究中出现的问题。无线网状网的系统结构和应用将被最先描述，之后将讨论影响协议设计的关键因素，理论上的网络容量，最后，将分别介绍无线网状网相关的试验台，工业实践和当前标准。 关键词：无线网状网；Ad hoc 网络；路由协议；传输协议；可扩展性 Investigate and Research for Wireless Mesh Network ?Abstract: Wireless mesh network (WMNs) consist of mesh routers and mesh clients, where mesh routers have minimal mobility and form the backbone of WMNs. They provide network access for both mesh and conventional clients. The integration of WMNs with other networks such as the Internet,cellular,IEEE 802.15, IEEE 802.16, sensor networks,etd., can be accomplished through the gateway and bridging functions in the mesh routers. Mesh clients can be either stationary or mobile, and can form a client mesh network among themselves and with mesh routers. WMNs area networks (WLANs), wireless personal area networks (WPANs), and wireless metropolitan area networks (WMANs). They are undergoing rapid progress and inspiring numerous deployment. WMNs will deliver wireless services for a large variety of applications in personal, local, campus, and metropolitan areas. Despite recent advances in wireless mesh networking, many research challenges remain in all protocol layers. This paper presents a detailed study followed by discussing the critical factors influencing protocol design. Theoretical network capacity and the state-of-the-art protocols for WMNs are explored with an objective to point out a number of open research issues. Finally, testbeds, industrial practice, and current standard activities related to WMNs are highlighted.
