Detecting a location of motion using wireless signals in a wireless mesh network that includes leaf nodes

A system comprising:

• a wireless mesh network comprising nodes connected by wireless links, the nodes of the wireless mesh network comprising a first access point (AP) node, one or more other AP nodes and leaf nodes, the wireless links comprising:
• wireless links between the first AP node and the one or more other AP nodes;
• and
• wireless links between the first AP node and a first subset of the leaf nodes;
• one or more processors;
• and
• memory storing instructions, wherein the one or more processors are configured to execute the instructions to perform operations comprising:
• obtaining motion-sensing data based on wireless signals exchanged on the wireless links;
• identifying, based on the motion-sensing data, the first AP node as an estimated location of motion of an object;
• in response to the first AP node being identified as the estimated location of motion, generating a likelihood data structure comprising likelihood values assigned to respective nodes of the plurality of nodes, the likelihood values assigned to the first subset of the leaf nodes and the first AP node being higher than the likelihood values assigned to other nodes in the wireless mesh network;
• determining a location of the motion of the object based on the likelihood data structure.

A non-transitory computer-readable medium storing instructions that, when executed by a data processing apparatus, cause the data processing apparatus to perform operations comprising:

• obtaining motion-sensing data based on wireless signals exchanged on wireless links in a wireless mesh network comprising a plurality of nodes, the nodes of the wireless mesh network comprising a first access point (AP) node, one or more other AP nodes and leaf nodes, the wireless links comprising:
• wireless links between the first AP node and the one or more other AP nodes, and
• wireless links between the first AP node and a first subset of the leaf nodes;
• identifying, based on the motion-sensing data, the first AP node as an estimated location of motion of an object;
• in response to the first AP node being identified as the estimated location of motion, generating a likelihood data structure comprising likelihood values assigned to respective nodes of the plurality of nodes, the likelihood values assigned to the first subset of the leaf nodes and the first AP node being higher than the likelihood values assigned to other nodes in the wireless mesh network;
• determining a location of the motion of the object based on the likelihood data structure.
