Research Of Secure Routing Protocol In Wireless Mesh Network

With the rapid growth of WLANs and 3G networks, wireless communication technologies are penetrating our life. As a result, how to provide wider wireless coverage with higher data rate, becomes the major demand of the next-generation wireless systems.As a newly developed wireless network, Wireless Mesh Network (WMN) characterized by distinguished features such as self-organization, self-healing, high spectral efficiency, wide coverage, high scalability, and high reliability, meets such a challeng in many ways. We are certain that WMN will be an important component in next-generation wireless system.WMN originates from the Ad Hoc network, and retains it's flexibility in choosing routes, while introducing many features of the Internet.Therefore, like the Ad Hoc network, it is very important to have an effective and secure routing mechanism to ensure successful operation of WMN. However, there are few results on the routing of WMN, most of which focus on improving performance of the protocols, and even less on the secure routing of WMN.In this work, we mainly study the scure routing of WMN. The architecture, feature, and key technologies of WMN are introduced first. Then, two well-known routing schemes for Ad Hoc networks, DSR and AODV, are discussed. Some secure routing mechanisms under these two schemes are presented, with emphasis on the authenticated routing of Ad Hoc network (ARAN). By analyzing the possible threats and characteristic of WMN, we propose ARWMN, an improved secure routing of WMN based on ARAN. Its performance is evaluated.
