作为一种新型的接入网技术,无线Mesh网络具有组网灵活、适应性强等特点,近年来得到了飞速的发展和关注。然而,对于研究和开发人员来讲,缺乏实际或与实际接近的验证和测试平台,难以确保实验的结论和效果的真实可靠性。在简要介绍无线Mesh网络特点,研究相关软件路由技术的基础上,利用Linux的开源特性,以DSR路由协议为例,提出了一种基于Click软件路由技术在Linux主机上实现无线Mesh网络节点的方法,并详细描述了节点的设计与实现方案。基于所开发的平台,不仅可以灵活地嵌入各种不同的功能模块,而且可以方便地搭建各种Mesh网络实验与测试平台。
As a new type of access network technology, wireless Mesh Network has the characteristics of flexible networking and strong adaptability. In recent years, it has been rapidly developed and focused. However, for research and development personnel, the lack of actual or close verification and testing platforms makes it difficult to ensure the reliability of experimental conclusions and effects. Based on the introduction of the characteristics of wireless Mesh network and the research of related software routing technology, taking the open source feature of Linux as an example, this paper presents a method of implementing wireless Mesh network node on Linux host based on Click software routing technology , And described in detail the design and implementation of the node. Based on the developed platform, it not only can flexibly embed various functional modules, but also can conveniently construct various Mesh network experiment and test platform.
