Performance evaluation and parameters estimation of the anti-collision protocol used in GB/T 28925-2012

GB/T 28925-2012 is a standard of P. R. China for active radio frequency identification (RFID). It defines wireless communications between reader and tag at 2.45GHz. Framed Slotted Binary Tree (FSBT) anti-collision protocol is adapted in it. However, performance of FSBT is not evaluated and parameters of FSBT are not estimated. A metrics for evaluating time performance and another metrics for evaluating energy performance were proposed with unknown number of tags. They were used to analyze and evaluate the performance as well as help in selecting parameters. Finally, simulation results indicate that this protocol has better performance than previous protocols. Its time metrics can achieve above 1.24, while binary tree is 0.96. Its energy metrics can achieve above 1.39, while dynamic frame slotted ALOHA is 1.09. Its system efficiency can achieve above 47% with unknown number of tags in large scale scenarios.
