Abstract

For low-cost RFID systems, the design of passive tags is a key issue in anti-collision protocols where lower power consumption allows a longer working distance between tags and the reader. In this paper, we look at anti-collision protocols in tags' processing for their power optimization. We propose a new criterion, which takes into account both energy consumption and time complexity, to evaluate anti-collision protocols. An improved protocol is also presented for power savings.
