Abstract An adaptive anti-collision algorithm is proposed in the paper. To overcome the disadvantage of ABS algorithm, the information of collision bits is used and an EPC search matrix is determined in the proposed algorithm. The concept of collision stack is put forward.Based on the states of timeslots, the search paths can be adaptively adjusted. Theory and computer simulation results show that the proposed anti-collision algorithm is practical and can greatly decrease collision timeslots, idle timeslots and communication load.
