In the recent few years, the UFH RFID systems which work in the frequency range between 860MHz and 960MHz have been widely adopted in real deployments and applications, and accordingly the EPC Gen-2 protocol is proposed as an international standard to resolve the tag collisions occurred in such system. In this paper, based on the stochastic distribution model established to analyze the collision resolution process of this protocol, some key factors that affect its performance are discussed, and a transmission control schema based on the stochastic model is proposed to optimize this protocol. Simulations are performed to examine this optimization and the its performance is verified regarding to the average number of queries to collect a tag identifier.
