多读写器环境下的RFID系统的抗干扰研究

Collosion problem of RFID system in multireader environment

针对RFID系统的多读写器环境提出了一种分时和色波算法相结合的抗干扰方法,解决了多读写器环境下的两种主要干扰:读写器对标签的干扰和读写器对读写器的干扰。仿真结果表明,该方法对于降低网络的重传指数有较好的性能。

Now the antieollision scheme in RFID network doesn＇t combine the consideration of reader-to-tag collsion with reader-to-reader collision. By making use of time division multiplex and colorwave algorithm a new antieollision scheme is introduced in this paper. The simulation shows that the performance of this scheme is good in reducing the retransfer index.
