Abstract

We propose a new algorithm for estimating the location of an outdoor RFID node, based on the received signal strength (RSS) of a transmitted message by a set of readers with known locations. The algorithm supposes omni-directional RFID readers that are prevalent for outdoor long range RFID systems. The method does not require knowledge of the Effective Isotropic Power (EIPR) of the transmitting tag, and bounds the position of the node within a small delimited candidate area. Our simulation results demonstrate that the Received Signal Compensation Based Localization (CBL) method outperforms other compared RSS-based methods in improving the precision of the bounded area.
