MR Mesh: A Multi-Radio Wireless Mesh Network Testbed

Wireless mesh networks (WMNs) are expected to be one of the next generation of wireless interconnection technologies. As to fully exploit the advantage of WMNs, a lot of research work has been done, e.g. new routing protocols, metrics, multiradio/multichannel WMNs, etc. In this paper we present a multiradio WMN testbed (called MR mesh) which was designed with purpose to study different routing protocols, metrics and channel selection/assignment algorithms or other strategies. MR mesh implements mesh functionality upon multiple 802.11 based wireless network cards. It is flexible to support different routing protocols, metrics, easy to implement channel assignment or radio selection algorithms, and simple to experiment network organization/management strategies.
