Due to collision and mobile problems, it is difficult to use a single reader to identify a large number of mobile tags successfully. In this paper, a new anti-collision scheme is proposed, which combines the tag anti-collision algorithm and multiple reader deployment to solve the mobile tag collision problem. This scheme adopts grouped dynamic frame slotted ALOHA algorithm based on CDMA to deal with the collision which is caused by that large amounts of tags response to the reader. And it adopts the power control algorithm based on cellular model to deal with the collision between the readers. The simulation results show that the total number of slots needed by the tag anti-collision algorithm is less than other similar algorithms; the cumulative adjustment times of reader anti-collision algorithm are less than other similar algorithms, and the algorithm is more stability. It has certain application value in practical engineering.
