Modeling Location Monitoring System Using Directional Antennas

RFID is fast becoming a part of all applications, which involve automatic identification and information retrieval. The more recent applications of RFID include garbage management and health monitor. In addition to the inventory and supply chain management applications for which it was originally designed, RFID can also be used for location tracking of objects. Use of RFID system for location tracking purposes helps increase supply chain and assembly line visibility. Indoor location sensing suffers from a variety of problems, which are absent in the case of outdoor location sensing. In our proposed system, we are going to use directional antenna along with RFID reader. In the proposed method, an RFID reader has multi-sensing ranges. Therefore the proposed method can perform the prompt positional estimation, i.e. the method can produce the accurate estimation of tag´s positions.
