Wireless Mesh Network (WMN) is a great technology for rapid deployment, high scalability, easy management and low cost. WMNs are dynamically self-forming, self-healing, and self-organizing. WMNs are formed by mesh routers and mesh clients. Mesh routers have minimal mobility and form the mesh backbone for mesh clients.

Actually, there are many on-going research projects on WMNs in academia, research labs and companies; such as MIT Roofnet, which is an experimental 802.11b/g mesh network currently under development at the Computer Science and Artificial Intelligence Laboratory of the Massachusetts Institute of Technology (MIT); USCB MeshNet, which is an experimental WMN deployed on the campus of the University of California, Santa Barbara (USCB); and Microsoft Research, which is working in a community mesh network. These projects are building mesh platforms based on off-the-shelf products and develop demanding applications and services.

Here, there are some WMNs Testbeds:
