A New Method in RFID Anti-Collision Protocol using Chaos Optimization Algorithm

Abstract

One of the main challenges in modern anti-collision algorithms in RFID systems is to estimate the number of collided tags in each slot of identification process. This paper presents a novel solution in Vogt tag estimation algorithm which is used in assigned tree slotted aloha (ATSA) method based on Chaos optimization algorithm. This method has been examined with logistic chaotic map and outcomes are compared with classical method. Simulation is accomplished with 12-bit ID which covers the full serial number bit length and the tags number are considered up to 4096 tags. Some criterions such as the number of collision slots, idle slots, and total slots are compared and simulation results show an improvement in system throughput.
