Abstract
Wireless mesh networks (or 'meshes') are enabled for arbitrary interconnection to each other and may provide varying levels of coverage and redundancy as desired. Interoperability between meshes having differing configurations, internal operations, or both, may be freely intermixed and inter-operated in unrestricted combination. Enhanced explicit inter-bridge control protocols operate using pre-existing control packets. Pre-existing broadcast packet floods are used to learn the best paths across interconnected meshes (termed a 'multi-mesh'). Enhanced routing protocols operating within each mesh may optionally examine information limited to the respective mesh when forwarding traffic, thus enabling robust multi-mesh scaling with respect to memory and processing time required by the routing protocols. Communication scalability is improved by enabling frequency diversity across the multi-mesh by configuring meshes within interference range of each other for operation at a plurality of frequencies. Each mesh may operate at a respective non-interfering frequency.
