摘要
Abstract
In certain emerging applications, RFID needs high efficiency of tag identification. In order to solve the tag collision problem when the number of tags is unknown and varies greatly, many tags reply to a reader at the same time to cause the conflict loss label information problem, we propose an enhanced Q algorithm. In this algorithm, the reader modifies the Q value according to the change of the tag number so that the identification efficiency is improved observably. The procedure of the algorithm is introduced in detail in this paper. An evaluative model for the system efficiency is built in order to obtain the optimal parameters in the new Q algorithm. The practice application proves that the algorithm can a-chieve better performance than the old Q algorithm and the adaptive ALOHA algorithm.关键词
