Abstract:
A method and system locates a position of a transceiver in a cooperative relay network of nodes. A primary node broadcasts a range request (RREQ) message. A target node, in response to receiving the RREQ message, broadcasts a range reply (RREP) message, wherein the RREP message includes a time difference between receiving the RREQ message and broadcasting the RREP message. A secondary node, in response to receiving the RREQ message and the RREP message, broadcasts a range data (RDAT) message, wherein the RDAT message includes a time difference between receiving the RREQ message and the RREP message. Then, a position solver can determine a location of the target node based on the time differences in the RREP message and the RDAT message.
