摘要
主要针对RFID系统中标签的碰撞问题,提出了一种分层式的二进制防碰撞算法,改进的算法通过一个生产随机数的寄存器对待识别的标签进行分层,并以随机数作为阅读器寻呼的索引,从而减少了阅读器的寻呼次数,然后将改进的算法与动态二进制数算法和跳跃式类二进制树算法对搜寻时间通过仿真做了对比。证明了改进算法的高效性。
This paper focus on the problem of tag collision proposes a layered binary anti-collision algorithm. The improved algorithm identifies the tags to be identified through a register producing random number, and the random number works as an index for reader paging. Consequently decrease the search times of reader. Then the improved algorithm is compared with the dynamic binary anti-collision algorithm and jumply similar binary anti-collision algorithm in terms of search time by using simulation technology. The result proves that the improved algorithm is high-efficiency.
