Abstract
Methods and systems of the present invention employ perturbation techniques for configuring RFID-tag-reader networks in order to achieve increased overall efficiency of a network of RFID-tag readers. According to described embodiments of the present invention, individual RFID-tag readers within a multi-RFID-tag-reader network may be removed or shut down, or RFID-tag readers may be displaced relative to one another, in order to remove interferences between RFID-tag readers and to increase the interrogation efficiency of the multi-RFID-tag-reader network. A method embodiment of the present invention schedules a multi-RFID-tag-reader network as a cycle of power-on/power-off intervals.
