摘要
随着WLAN的飞速发展,无线Mesh网络技术成为人们日益关注和研究的焦点,各种方法已被广泛用于无线Mesh网络的研究,主要包括有理论分析、仿真、模拟、虚拟和真实测试平台。
本文首先对比总结了这些研究方法的优缺点,然后结合研究目标,提出利用真实测试平台的方法来研究WLAN Mesh网络的相关性能,这样所得到的各种参数最能反映网络运行的真实状况,其结论的适用性也最强。
由此,本文提出一种性能测试平台的构建方案,在明确平台设计目标及原则的基础上,给出平台的系统设计,其逻辑结构分为物理、运行、网络、测试和管理环境五部分,并详述了各部分的功能框架。进而从网络规划和关键技术的层次结构两方面给出了实现方案。
最后,在设计和实现方案的指导下,完成了性能测试平台的搭建,并通过功能测试及结果分析,验证平台功能的完整性和有效性。
With the rapid development of wireless local networks (WLAN), Wireless Mesh Network (WMN) technology has increasingly attracted people’s attention and become the focus of research community. A variety of approaches have been applied to the study of wireless mesh network, including theoretical analysis, simulation, emulation, virtualization and real testbed.
This paper firstly compares and summarizes the advantages and disadvantages of these approaches. Secondly, according to the study objectives, we propose to build a testbed to study the performance of WLAN mesh network, thus the parameters obtained reflect the runtime status best and its conclusions are of great applicability and accuracy.
Therefore, this paper proposes the solution for the construction of a testbed. On the basis of the design goals, the overall framework is presented, whose logical structure consists of five parts, namely physical, network, runtime, testing and management environments, and functional framework of each part is given in detail. Then the realization scheme is described in network planning and layered structure of key technologies of the testbed.
Finally, following the design and realization scheme, we have completed he construction of our testbed. The integrity and effectiveness of our testbed is verified through function testing and analysis.
