Energy Based Performance Evaluation of Passive EPC Gen 2 Class 1 RFID Systems

This paper analyzes performance of RFID networks that are based on passive tags using EPC Gen2 Class1 communication protocol. For the first time, all the main factors impacting tag read efficiency and read latency are considered - inclusive of MAC layer collision, link layer packet loss and the impact of the use of energy harvesting in passive tags. Specifically, the impact of tag {duty cycling} due to limited harvested energy is considered - a first in the analysis of RFID systems, to the best of our knowledge.
