Method and system for target positioning and tracking in cooperative relay networks
First Claim
1. 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.

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.

11. A system for locating a position of a transceiver, in a cooperative relay network of nodes, comprising:
-
a primary node in the cooperative relay network is configured to broadcast, a range request (RREQ) message; a target node in the cooperative relay network is configured to broadcast, 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; a secondary node in the cooperative relay network is configured to broadcast, 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 a position solver of the cooperative relay network determines a location of the target node based on the time differences in the RREP message and the RDAT message.
