Claim 0:
1. A method of operations by a wireless device, comprising:
determining a time of reception and received signal strength indicator (RSSI) associated with each of a plurality of data packets received from one of a plurality of wireless sensors, wherein the RSSI of a data packet received from one of the wireless sensors depends on an angular position of a second sensor associated with the one wireless sensor, wherein each of the plurality of wireless sensors is associated with a respective one of a plurality of second sensors;
determining, for each of the plurality of data packets received, angular positions of every one of the plurality of the second sensors at the time of reception of the data packet to generate estimated angular positions of the plurality of second sensors when the data packet is received;
determining RSSI signatures of variations of the RSSI over a range of the angular positions based on the RSSI of the plurality of data packets and the estimated angular positions of the plurality of second sensors; and
determining an estimated association between the plurality of wireless sensors and the plurality of the second sensors based on the RSSI signatures.
