Effective Bandwidth Path Metric and Path Computation Method for Wireless Mesh Networks with Wired Links

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.
