ABSTRACT:
A method, apparatus, and system for the selection of target nodes in locating a receiver is disclosed. The receiver measures the strength of signals transmitted by a number of nodes. The received strength is subtracted from the transmitting power of the nodes to determine the respective path losses. The node with the lowest path loss is selected as the target node. The target node is then used to perform a triangulation for determining the location of the receiver.
