Abstract: As an important branch of RFID anti-collision algorithm, binary searching anti-collision algorithm has been facing many new problems when RF)D is been widely used in supply chain for items management Based on the introducing about the traditional binary searching algorithm, the writer designed an improved adaptive binary searching algorithm concerning with system efficiency, consumer privacy and system flexibleness. The writer proved the correctness of the improved adaptive binary searching algorithm with the simulated C program and the theoretical analysis, and comparcel the main performance improvement of the improved adaptive binary searching algorithm with the conventional binary searching algorithm.
