Abstract :
Many systems exist (TOA, AOA, RSSI) that can be used with diverse technologies (ultrasounds, infrared, Bluetooth, 802,11...) for indoor location. In this article we choose to apply TOA on a ZigBee network, to be able to add useful functionalities for other applications in an existing network and, in addition, achieve minimum consumption and low cost. The results that we find are promising, because we obtain a precision within a meter in 90% of the cases.
