Improvement of RFID tag detection using smart antenna for tag based school monitoring system

Radio Frequency Identification (RFID) technology has attracted much attention due to its variety of applications in different fields e.g. military, sports, security, airline, inventory control, object tracking etc. Comparing to other tracking and detecting system such as barcode or smart card systems, RFID is faster and efficient. In this paper we present an efficient method of RFID tag detection for monitoring school going kids, by implementing smart antenna technology along with providing the updates to their parents. While this is an effective approach for the security and management of school going kids, we have to consider the coverage area and efficient tag detection issues. One important problem in RFID systems is to optimize the power allocation to the tag with respect to their distance from the reader which results in efficient tag detection and distance coverage. In this paper, we proposed an efficient and improved approach to fulfill these requirements for efficient tag detection. Results from mathematical analysis and extensive simulation demonstrate that our scheme shows a significant improvement over the traditional approaches of tag detection and power allocation techniques.
