On the basis of the anti-collision algorithm of the binary tree and the quadtree query tree, the methods of locking the collision bit and predicting the child node are used, a new lock-bit hybrid querytree (novel lock-bit hybrid query tree, NLHQT) algorithm is proposed. In the algorithm, the collision bit information is extracted through the lock instruction, and the extracted collision bit information is predicted. While reducing the collision time slot, the reader generates a new query prefix through prediction, thereby avoiding the generation of idle child nodes. Compared with the improved hybrid query tree (IHQT) anti-collision algorithm and the regression lock adaptive multi-tree search (RLAMS), the algorithm in this paper is more effective in reducing the total number of time slots and communication complexity, and the efficiency of identifying tags can be effectively improved.<\/jats:p>","DOI":"10.3233\/rft-221502","type":"journal-article","created":{"date-parts":[[2023,3,3]],"date-time":"2023-03-03T10:51:23Z","timestamp":1677840683000},"page":"21-36","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["A RFID anti-collision approach for efficient query tree"],"prefix":"10.1177","volume":"13","author":[{"given":"Gang","family":"Li","sequence":"first","affiliation":[{"name":"Hunan International Economics University, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingfang","family":"Wang","sequence":"additional","affiliation":[{"name":"Hunan International Economics University, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,3,2]]},"reference":[{"key":"ref001","doi-asserted-by":"crossref","unstructured":"Barletta,L., Borgonovo,F., Filippini,I.
