摘要
为促进RFID系统识别性能的有效提高并减小算法复杂度,构建一种双前缀探测方法(DPPs)来使RFID系统达到更高的识别效率,利用DPPs可以实现在同一时间中快速识别多个标签。该DPPs算法能够有效降低识别通信时间并达到更少的读写器查询次数。分别利用计算时间步,识别效率、吞吐率来评价DPPs算法性能:DPPs算法可以通过比其他算法更少的时间步来识别数量相同的标签;各种算法的吞吐率基本都达到0.5以上,DPPs算法可以达到100%的最大吞吐率,明显超过其他算法;DPPs算法具有比其他算法更高的时间效率,且在各项性能指标下都可以实现稳定优势。
In order to effectively improve the RFID system identification performance and reduce the algorithm complexity,a double prefix detection method(DPPs)is constructed to achieve higher identification efficiency of the RFID system.DPPs can be used to quickly identify multiple tags at the same time.The DPPs algorithm can effectively reduce the recognition communication time and reduce the number of reader queries.DPPs algorithm can recognize the same number of labels by less time than other algorithms.The throughput rate of each algorithm is basically above 0.5,and DPPs algorithm can achieve 100%maximum throughput rate,which is obviously higher than other algorithms.DPPs algorithm has higher time efficiency than other algorithms,and can achieve stable advantages under various performance indexes.
