This paper firstly analyses the performances of several RFID anti-collision algorithms under the environment of dense tags. The performances discussed include total time consumed
system efficiency
total bits transmitted by the reader and average bits sent by each tag and so on. Then a novel improved algorithm based on ALOHA algorithms is present. The new algorithm has high system efficiency around 0.41 and less amount of data transmitted which is decreased by 50 percent at least compared with treebased algorithms. Lastly
conclusions are made and directions of further work are given.
