RFID系统时隙不完全竞争防碰撞算法
Slot Partial Competitive Anti-collision Algorithm for RFID System
摘要
Abstract
Based on the ISO/IEC 18000-6C UHF Radio Frequency Identification(RFID) standard, this paper proposes a Slot-based Partial Competitive(SPC) anti-collision algorithm, which introduces dynamic binary tree search technology into the competitive collision avoidance mechanism for the first time. Moreover, the SPC algorithm applies the specific technologies to idle slots and collision slots. The performances of the dynamic binary tree search, ISO/IEC 18000-6C and the SPC algorithm are compared via NS-2 simulation experiments. Simulation results indicate that the SPC algorithm is able to not only reduce the recognition time by 30％ and 20％ compared with the binary tree search algorithm and the 18000-6C algorithm, respectively, but also improve the recognition rate by 35％ compared with 18000-6C algorithm.关键词
