An Investigation on Tree-Based Tags Anti-collision Algorithms in RFID

The tree-based tags anti-collision algorithm is an important method in the anti-collision algorithms. In this paper, several typical tree algorithms are evaluated. The comparison of algorithms is summarized including time complexity, communication complexity and recognition, and the characteristics and disadvantages of each algorithm are pointed out. Finally, the improvement strategies of tree anti-collision algorithm are proposed, and the future research directions are also prospected.
