摘要
文章建立在OPNET RFID原型的基础上,针对具有帧时间间隙的Aloha算法,分析在不同负载条件下具有最高系统识别率的帧长。在此基础上,分析动态DFSA框架的性能。通过比较固定帧长为8和16的RFID系统的识别率和相关曲线发现,当要识别的标签数量很大时,基于DFSA算法的RFID系统的识别率要高得多。
Based on the OPNET RFID prototype,this paper analyzes the frame length with the highest system recognition rate under different load conditions for the Aloha algorithm with frame time gap.Based on this,the performance of dynamic DFSA framework is analyzed.Through comparing the recognition rate and correlation curve of RFID system with fixed frame length of 8 and 16,it is found that when the number of labels to be recognized is very large,the recognition rate of RFID system based on DFSA algorithm is much higher.
