基于Click的Mesh路由平台设计与实现

Design and Implementation of Flexible Routing Testbeds for Wireless Mesh Networks based on Click

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 access-network technology,WMN（Wireless Mesh Networks） with such characteristics as flexible networking and well-adapted capability,develops rapidly in recent years.However,due to the lack of actual or close-reality verification and test platform,the developer is hard to ensure the authenticity and reliability of the experiment conclusions.This paper briefly describes the characteristics of WMN and explores the related technology of the software routing,then with DSR routing protocol as an reference,proposes an approach to implementing the WMN node on Linux hosts based on routing technology of Click software,and tells of the design and implementation of the mesh node.The approach can flexibly embed a variety of functional modules and easily build up various test and experiment platforms for Mesh networks.
