Energy consumption evaluation framework for passive RFID tag anti-collision algorithms

摘要

In passive RFID systems, tag receives energy for communication from the reader, in the absence of on-chip energy source. Hence, a good amount of energy is needed to be transmitted by the transceiver circuit to provide energy to the transponder. Hence, circuit-level energy consumption cannot be ignored in the total energy consumption evaluation of passive RFID systems. Previously, energy consumption evaluation for passive tag anti-collision algorithm has been done ignoring circuit-level energy consumption values. This may provide inaccurate results. Here in this paper, an energy consumption evaluation framework for EPC class 1 Gen 2 (passive) based tag anti-collision algorithm has been proposed. This proposed framework includes energy consumed by transceiver and transponder circuits, in total energy consumption estimation for better accuracy.
