By considering the redundant time and the theoretical maximum system efficiency value, the DQA algorithm is proposed after optimized by grouped and dynamic Q method. Simulation results show that the proposed algorithm, compared with the traditional anti-collision algorithms, obtains a high system efficiency which maintains at 0.368 and shows the superiority in the time slots saving and redundant time reducing. What is more, the algorithm takes EPC-C1G2 protocol into account which contributes to the arithmetic replant.
