In this paper, an Adaptive n-Resolution scheme (AnR) is presented for RFID tag identification. The proposed protocol first divides target tags into two categories: staying tags and new arriving tags. Then two distinct identification processes are in-voked in sequence to recognize tags in the two tag groups. Based on our theoretical analyses and simulation experiments, AnR reduces at least 10% on communication overhead and 10% to 40% identification delay in comparison with Pair-Resolution Blocking algorithm [1-2].
