RFID系统中二进制搜索防冲撞算法研究
Research on Binary Searching Anti-collision Algorithm in RFID System
摘要
Abstract
To solve the problem of Radio Frequency Identification(RFID) tag collision. An improved binary search anti-collision algorithm is proposed. The algorithm uses the Manchester coding to identify collision bits, only transmits collision bits to decrease the total amount of data transmission. It also introduces dormancy counter to reduce the total quantity of transmission. And it adopts back-off strategy to reduce the number of reader requisition commands. Simulation results show that it can effectively reduce the number of search and delay and improve the recognition efficiency of RFID system.关键词
