Abstract:
1. A robust, wireless mesh network comprising: a plurality of quasi-static routers wherein each of said quasi-static routers are connectable to a plurality of directional antennas providing broadband communications via point-to-point connections during a link or a node failure; a controller that: determines, when preserving a two-edge network connectivity during the link failure in the network of quasi-static routers, a first number of the plurality of directional antennas based on determining a first bounded node degree, unit disk graph subgraph providing two edge-disjoint paths between every pair of the plurality of quasi-static routers in the first subgraph, wherein the number of determined directional antennas is at least ten, and connecting the quasi-static routers with the first determined number of directional antennas; and determines, when preserving a two-node network connectivity during the node failure in the network of quasi-static routers, a subset of the plurality of directional antennas based on determining a second bounded node degree, unit disk graph subgraph providing two router-disjoint paths between every pair of the quasi-static routers in the second subgraph, wherein the subset of determined directional antennas is at least six, and connecting the quasi-static routers with the subset of directional antennas.
