Interference management in a multi-hop wireless network

Abstract:

In one embodiment, an interference-management system of a multi-hop wireless network may access an interference map indicating interference among network nodes, each network node comprising sectors that each comprise an array of beamforming antennae. The interference-management system may identify links between network nodes, each link being associated with a transmitting (TX) beamforming weight variable and a receiving (RX) beamforming weight variable. The interference-management system may generate a factor-graph representation of the multi-hop wireless network comprising a first set of vertices corresponding to a second set of vertices, each vertex pair being associated with an identified link, wherein each vertex pair comprises a variable node and a function node, and wherein messages passed between the nodes of a first vertex pair are derived at least in part based on messages previously passed between the nodes of one or more vertex pairs.
