| Abstract: | The key technology in reading multiple tags simultaneously is to find an Anti-collision algorithm to solve the data transmission collision in RFID system. This paper first studies several Slotted ALOHA based Anti-collision algorithms, then compares ,analysis and gives out the simulation results; Second, the paper evaluates the influence on the total delay of identification and system efficiency when we try in different ways on tag estimation and frame size adjustment; Finally, the paper further simulates and analyses the adaptive adjustment Anti-collision algorithm, and gives out the results as well. |
| Keywords: | Anti-collision algorithm RFID ALOHA Tag Estimation Frame Size Adjustment Adaptive adjustment |
