Patent ID: 8005486

Claim:
A method for determining a position of a node in a network, comprising: providing a plurality of anchors having a known position, each anchor transmitting a position signal indicating the position of the respective anchor; positioning at least one non-anchor node within signal range of the anchors; receiving, at the at least one positioned non-anchor node, at least one of the position signals from the anchors; determining from a signal strength (QoL) of the received signals a quality of position estimate (QoE) for the at least one non-anchor node; comparing the determined QoE for the at least one non-anchor node with QoE values for others of the at least one non-anchor node; and upgrading one of the at least one non-anchor nodes to serve as an additional anchor based on the comparison of the QoE values for the non-anchor nodes, wherein in response to the upgrading, the upgraded node begins transmitting a position signal indicating its position.
