Based on RFID Technology of High-Speed Mobile Multi-Objective Binary Tree Anti-Collision Algorithms

Abstract

In the RFID radio frequency identification system, multiple targets at high speed mobile position data transfer at the same time of channel conflict, and solving multi-objective channel conflict is the most effective method is through the anti-collision algorithm. This article will analysis RFID technology in high speed moving target in the cause of the conflict, this paper introduces the existing anti-collision algorithm and its related optimization algorithm, the paper proposes a kind of suitable for high speed mobile multi-objective binary anti-collision search algorithm for continuous collision position for parity coding mode group, through to the conflict area target estimate size to reduce the number of queries to the effective time identify multiple high-speed moving targets, can better in high speed moving target recognition application. Maltab simulation results show that the proposed algorithm outperforms the other binary tree anti-collision algorithm in effective recognition time etc are obviously improved.
