An improved ALOHA RNS(Random Number Slot) algorithm was proposed based on the analysis of ALOHA Bit-Slot algorithm.The algorithm changed the return method of tag data,reduced the data between tag and reader,shortened the recognizing time,improved the system throughput rate,and solved the problem of current reader which could not detect more than one tag responsing the same unique code.Under a large amount of tag,it dynamically classifed the number to fit large data transmission.The simulation results show that the improved RNS algorithm improves the system throughput rate by 30 percent compared with Bit-Slot algorithm,when tag number is more than 1 000.It is suitable to large amount of data and real-time RFID environments.
