An anti-collision scheme for the radio-frequency identification system is used to guarantee that all the tags in the reader field are identified.This paper develops an efficient anti-collision algorithm based on the tree search algorithms to improve the performance of the RFID system.The improvement is achieved by means of the manner of the requests' building and the mapping of collision bits.Taking into account the average request cycle and the length of transmitted data

this scheme has been designed to complete identifying all tags.The simulation results demonstrate the effectiveness of the proposed scheme in terms of time complexity

communication overhead and energy efficiency.
