Research on the Received Signal Strength Indication Location Algorithm for RFID System

Received signal strength indication (RSSI) location algorithm is studied in this paper. Simulation platform of radio frequency identification (RFID) location system is also constructed. The affection by different number of reference tags with detection power-level is studied. Tracing location information of mobile tags and the layout of simulation area to effect location error are also investigated. The simulation results illustrate that RSSI algorithm based on RFID with active tag is a viable and cost-effective candidate for indoor location sensing
