Tag collision is one of the most important issues in RFID systems and many tag anti-collision protocols were proposed in literature. But some kind of these protocols like tree-based protocols (specifically query tree) which its performance depends on tag ID length and construction have some issues like ID distribution. In this paper the authors discuss about Query tree protocol which may influenced by ID distribution. Then they propose a novel type of this protocol called informatics query tree to solve it. Then they evaluate the performance of presented protocol to approve its benefits.
