Abstract
A system for an access node coupled to a computer to wirelessly communicate with a plurality of disparately located radio nodes each coupled to a meter or other sensor is provided. The radio nodes within the communication range of the access node orient onto a first logical layer to directly communicate with the access node. Additional radio nodes beyond the communication range of the access node indirectly communicate with the access node by detecting communications from radio nodes on lower logical layers that are closer to the access node and selecting a radio node of the detected radio nodes to be a repeater node. The selected repeater node has available memory capacity and a suitable power number to qualify as a repeater, which may periodically change. Sensed data is directly or indirectly communicated to the access node for further communication to a backend system computer.
