<正> For low-cost RF-ID systems, the power consumption of passive tag is a key issue. Playing the most important role in tag's base-band processing, anti-collision protocols (as well as their implementing circuits) need much endeavor for the optimization on power. In this paper, instead of carrying out the power optimization on protocol level or circuit level separately, we combine them to search for better solutions. We propose a new criterion, which takes into account both time and energy consumption, to evaluate anti-collision schemes. Simple as it may appear, it has good physical explanation, rather than a mechanical trade-off between power and time. We put forward an improved anti-collision scheme, and compare it to two existing and recommended anti-collision schemes.
