An anti-collision algorithm based on continuous slot detection

Abstract

In order to further increase the speed of tag identification, for solving the insensitivity of the frame adjustment in dynamic frame slot aloha algorithm and the high computing complexity of the Q value adjustment in Q algorithm, a new anti-collision algorithm, called continuous slot detection(CSD), is proposed. The idea of algorithm and the process of operation are introduced. In this algorithm, the optimal efficient is obtained by detecting the status of consecutive slots in frame and setting frame length by rules. The simulation results show that compared with other anti-collision algorithm, the proposed algorithm can decrease identification delay by 4% and increase identification speed by 6%.
