基于分组的动态帧时隙ALOHA防碰撞算法研究
Research on Tag Anti-Collision Algorithm Based on Dynamic Frame Slotted ALOHA
摘要
Abstract
In RFID systems, the collision resulted from tags has been a major factor affecting system performance. In order to further improve the identification efficiency of tag anti-collision algorithm in RFID system,it proposes an improved packet dynamic frame slotted ALOHA algorithm based on the analysis of the existing ALOHA algorithm. The proposed algorithm uses a new grouping method to improve the reader's identification efficiency of tag. When the number of tags is larger than 2S6, the algorithm can effectively reduce the reader's recognition time, improving the efficiency of the RFID system. Simulation results show that the proposed algorithm reduces the system slot time by 43% and 39% respectively compared with the basic framed slotted ALOHA algorithm and dynamic framed slotted ALOHA algorithm when the number of tags is 1000.关键词
