【Abstract】 In order to solve the problem of low throughput and packet delivery rate in RFID reader writer antenna networking due to interference signals, a new UHF RFID reader writer antenna networking method is proposed. At first, UHF RFID reader was subject to the co-channel interference through compressed wavelet, and then the anti-interference effect of the reader can be improved. After that, the propagation model of RFID reader antenna was discretized. Moreover, the problem about reader deployment was described in the form of discrete dot-matrix. Furthermore, the particle swarm optimization was used to convert the problem of reader deployment into a problem about discrete optimization. Meanwhile, the particle swarm optimization was used to solve the problem, and thus to obtain the optimal structure and size. Finally, the networking was achieved. Experimental results show that the proposed method has high packet delivery rate and large throughput, and can obtain a satisfactory networking scheme of UHF RFID reader antenna.更多还原
