Abstract
In last decade, indoor localization of target objects has been intensively studied. In particular, schemes that use RFID tags for precise localization of sensor nodes have received more interests. 3D localization based on RFID tags in indoor environments has not been enough studied. In this paper and at the attempt of contributing in this topic, we propose an approach based on MDS for 3D localization using active RFID tags in indoor environments. The considered system is a centralized scheme that involves a server, readers and tags. The propagation model used to estimate the received power considers the path loss and shadowing effects. To show the accuracy of the proposed scheme, a selection of numerical results is used.
