Power efficient anti-collision algorithm for RFID technology with added data security feature and its Implementation in VHDL

摘要

In the field of RFID technology, a power efficient tag anti-collision protocol plays an important role in the entire system based on this technology. The query Tree scheme is one of the most important anti-collision protocols for RFID technology. Researchers have developed different Query algorithm with improved features, each time reducing the number of query iteration and idle slots. The EPC Gen protocol uses this anti-collision algorithm, which is popularly known and globally accepted for its secured data transmission feature but having a huge load of data itself. Low power design and implementation of the anti-collision protocol is another challenging area for cost effective RFID system. In our research work, we have implemented the protocol as low power single chip solution. Furthermore, we have included a data security scheme in this protocol for secured data transmission. VHDL code has been used for design purpose, Xilinx ISE 14.3 simulation tools to simulate the design and Kintex-7 FPGA board for implementation purpose. We have also implemented other anti-collision protocols with different bit size and a comparative study of performance evaluation has been provided.
