Abstract
An improved algorithm of anti-collision algorithm is used to solve the collision problem existing in RFID system effectively.Firstly,several frequently-used binary anti-collision algorithms is analyzed and compared.By using the backward principle,the recorded collision information,the uniqueness identifies tags and grouping method to identify.The results of experimental simulation show that the query times of the new algorithm is 2/7 times than that of Return type algorithm,the length of transmitted datum of the new algorithm is being reduced by 59 percent over common binary anti-collision algorithm.
