HYBRID ZIGBEE RFID FOR DETECTION OF ACTIVE TAGS AND ENERGY MINIMIZATION

Abstract

Radio Frequency Identification (RFID) is the wireless use of electromagnetic fields to transfer data for the purpose of automatically identifying and tracking tags attached to objects. These tags contain electronically stored information and each tag has a unique identification number. RFID can support automatic information tracing and management during the identification process in many fields. Minimization of energy in RFID active tags plays a vital role in RFID management system. We propose a hybrid method for energy minimization using Zigbee integrated with RFID. The combination of RFID and ZigBee can be done with a very simple set up and it can manage all the data transmissions with very few bytes. Zigbee is used because it is a low power device and operates in beacon mode. Zigbee coordinator is responsible for managing and controlling the entire system. It transmits the data received by one reader to another thus eliminating redundant tag information from all the readers. Collision among tags is minimized thus increasing the throughput of the system.
