A Divide-and-Conquer Technique for Throughput Enhancement of RFID Anti-collision Protocol

A novel anti-collision technique is proposed to maximize identification performance in slotted Aloha based radio frequency identification (RFID) systems. We observe that much higher throughput can be achieved by identifying tags in a divide-and-conquer method, in which the set of tags is partitioned into multiple subsets of roughly equal size and then each subset is identified in sequence. Numerical results show that the throughput performance of our proposal outperforms existing methods by a significant margin.
