Patent ID: 8259699

Claim:
A method for locating a position of a transceiver, in a cooperative relay network of nodes, comprising: broadcasting, by a primary node in the cooperative relay network, a range request (RREQ) message; broadcasting, by a target node in the cooperative relay network in response to receiving the RREQ message, a range reply (RREP) message, wherein the RREP message includes a time difference between receiving the RREQ message and broadcasting the RREP message; broadcasting, by a secondary node in the cooperative relay network in response to receiving the RREQ message and the RREP message, a range data (RDAT) message, wherein the RDAT message includes a time difference between receiving the RREQ message and the RREP message; and determining, in a position solver of the cooperative relay network, a location of the target node based on the time differences in the RREP message and the RDAT message.
