In the wireless network of RFID system, the performance of data transmission can be measured by: efficiency performance and safety performance 。 Efficiency performance’s content includs transmission rate, transmission energy consumption per unit time, the amount of data transmission and so on. Safety performance measures the safety degree of data transmission. In order to improve the performance of RFID data transmission, this paper research on the efficiency and safety problems. So this paper main contens includes:1. Study on the optimization technology of RFID data transmission. The data transmission optimization means some related technologies which can be used to improve the performance of data transmission in the process. In order to optimize the efficiency of data transmission, this paper proposes three anti collision algorithms:1)In order to reduce the number of commands what are required for identification the tag, and also in order to improve the success rate of data transmission, new tag anti-collision algorithm is proposed in this paper which is named Impreoved BDBS(IBDBS). The theory which is named Select-ALL-Is-Best is introduced in IBDBS algorithm. SAIB can decrease the amount of data for identification tag in the transmission process. Through mathematical proof and simulation experiments, the result shows that IBDBS algorithm’s performance is better than other algorithms.2)In order to reduce the average recognition time and improve the success rate of data transmission, a new tag anti-collision algorithm is proposed in this paper which is named Impreoved Collision Tree(ICT). The theory which is named Extensive Select-ALL-Is-Best(ESAIB) is introduced in IBDBS algorithm. Through mathematical proof and simulation experiments, the result shows that ICT algorithm has better data complexity and time complexity than other algorithms.3)At the same time, this paper presents a new reader anti-collision algorithm which is named Identity of Competition and Collaboration for RFID Anti-collision(IC2RA). IC2 RA algorithm which is improved upon Pulse algorithm uses the idle reader to receive the tag message, and then the tag message will be transferred to the backend system. In this way, IC2 RA optimizes the amount of data transmission in per second and the recognition efficiency. In the simulation experiments, the result shows IC2 RA algorithm has certain performance advantages.2. Study on data transmission security technology. Data transmission security technology refers to some related technologies what can improve data transmission security. In order to improve the security of data transmission, this paper makes research on the RFID security vulnerability scanning technology, and proposes a vulnerability scanning algorithm which is named Vulnerability Scanning algorithm based on Attack Graph(VSAG), and the VSAG algorithm is used in the platform.In summary, IBDBS, ICT, IC2 RA anti collision algorithms optimize the efficiency of RFID data transmission. The VSAG algorithm improves the security of data transmission. So, the research contents of this paper improve the performance of RFID data transmission.
