Abstract：Collision issue is a significant one which limits the reading efficiency of RFID systems. This paper presents two new anti-collision protocols - CDCA protocol and CDCA-2D protocol. Detailed theoretical analysis and optimization for the two protocols are provided in this paper. The new protocols split the reading process of RFID systems into two steps. The collision information is obtained in the first step and then applied to make the second reading step completely collision-free. The simulation results denote that the new proposed protocols highly improve the reading efficiency comparing to the current popular anti-collision algorithm.
