Introduction Wireless mesh networks (WMNs) are dynamically self-organized and self-configured‚ with the nodes in the network automatically establishing an ad hoc network and maintaining the mesh connectivity. WMNs are comprised of two types of nodes: mesh routers and mesh clients. Other than the routing capability for gateway/bridge functions as in a conventional wireless router‚ a mesh router contains additional routing functions to support mesh networking. Through multi-hop communications
