摘要： Enhanced mesh network performance is provided by computation of a path metric with respect to multi-hop paths between nodes in a mesh network and determination of a path through the mesh network that is optimal according to the path metric. Information is communicated in the mesh network according to the determined path. Nodes in the mesh network are enabled to communicate via one or more wireless links and/or one or more wired links. The path metric optionally includes an effective bandwidth path metric having elements (listed from highest to lowest conceptual priority) including an inverse of a sustainable data rate, a number of wireless links, and a number of wireless and wired links. The sustainable data rate is a measure of communication bandwidth that is deliverable by a path for a period of time. Accounting is made for interference between contiguous wireless links operating on the same channel.

摘要： In a mesh network composed of multiple-radio nodes, we assign each radio to one of a plurality of channels, and treat a plurality of links between a pair of nodes as one logical link (bonded link). In some embodiments, the routing protocol is adapted to view each bonded link as one link having a combination of at least some of the properties of the constituent physical links. Traffic sent along a path is dynamically load balanced between the interfaces at each intermediate node based on the current utilization of each interface. In at least some embodiments, route discovery packets record the metrics of each component link of the bonded links leaving a node, but only one route discovery packet per pair of nodes is forwarded, reducing the route discovery packet traffic compared to if each route discovery packet were forwarded over each component link between the pair of nodes.

摘要： 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.

摘要： Techniques are described for automatically determining quasi-static per-link channel assignments for each radio in multiple-hop mesh networks having nodes with two or more radios and where only a small number of channels is available for use in the network. The method optimally assigns the channels to the radios of all of the nodes in the network so as to achieve the lowest interference among links and the highest possible bandwidth.

摘要： Various embodiments implement a set of low overhead mechanisms to enable on-demand routing protocols. The on-demand protocols use route accumulation during discovery floods to discover when better paths have become available even if the paths that the protocols are currently using are not broken. In other words, the mechanisms (or “Route Optimizations”) enable improvements to routes even while functioning routes are available. The Route Optimization mechanisms enable nodes in the network that passively learn routing information to notify nodes that need to know of changes in the routing information when the changes are important. Learning routing information on up-to-date paths and determining nodes that would benefit from the information is performed, in some embodiments, without any explicit control packet exchange. One of the Route Optimization mechanisms includes communicating information describing an improved route from a node where the improved route diverges from a less nearly optimal route.

摘要： Methods and systems for mobility of mobile nodes in mesh networks are taught wherein the mobile mesh nodes choose an attachment point to another mesh node based on predetermined criteria, such as the characteristics of the attachment point's path to a reference destination, and other factors local to the attachment point, such as load and available capacity. The mobile nodes forward packets on each other's behalf. Static and mobile nodes and the links between them are treated differently from each other in view of their respectively different properties. A special metric is used for paths that include mobile links in addition to the static mesh links and wired mesh links. Mobility is handled completely transparently to any client devices attached to the mesh nodes, where this attachment could be wireless or wired.
