Positioning with moving IEEE 802.15.4 (ZigBee) transponders

Abstract

In an ever-increasing number of wireless communications applications the measurement of positions of transmitters distributed in space is desired. Demands on low cost and power consumption make solutions that allow positioning with existing communications hardware during the process of data transmission particularly interesting. In this paper we discuss a method for using IEEE 802.15.4 (ZigBee) transmitter nodes with a special frequency-hopping scheme for this purpose and show the insensitivity of this method to transmitter motion mathematically as well as by exemplary simulations and measurements.
