无线网状网络路由安全协议综述

A Survey of Routing Security for Wireless Mesh Networks

无线网状网络(Wireless Mesh Networks,WMN)是近年来得到长足发展的一项新兴技术。它是一种分布式的无线网络,并将Ad hoc以及WLAN的优势结合起来,因此具有很广阔的应用前景。然而,目前的WMN技术还不够成熟,存在诸多安全问题,如何完善网络中的安全机制就成了目前研究的重点之一。本文从介绍WMN的基本结构开始,逐步介绍其安全性所面临的问题,以及各种安全的路由协议,最后对一些路由安全协议进行对比分析。

Wireless Mesh Network （WMN） is an emerging technology that has developed a lot these years. It is a distributed wireless network which combined the advantages of both Ad hoc and WLAN, thus having a broad application prospects. However, many security problems revealed the shortcomings of recent technology. As a result, it＇s important that we should improve the security mechanism in WMN. Started with introduction to basic structure of WMN, this article focuses on security problems in MWN and several security routing protocol.
