摘　　要：已有的RFID阅读器防碰撞算法一般仅可解决部分类型的阅读器碰撞,或者由于采用中心控制设备导致延迟较高,对此提出一种分布式的全类型RIFD阅读器碰撞解决方案。设计了一种分布式多信道通知协议,主要包括询问与接收两部分,从而合理地分布阅读器间的网络资源,在考虑全部阅读器碰撞类型的前提下,降低所有标签的平均询问延迟。仿真实验结果表明,本算法可解决全部类型的RFID碰撞,同时具有较低的延迟。The existing anti- collision algorithms for RFID reader can only resolve some types of reader collisions, or it has high delay due to adopting centralized control hardware, a distributed anti method for all types of RFID reader collision is proposed for that problem. A distributed multi- channel notification protocol is designed, which includes two parts of interrogation and receive,and the network resource for the readers is distributed reasonably. All types of collisions are considered by the proposal and the average tag interrogation delay of all tags are reduced. Simulation experiments results show that the proposal can handle all types of collisions and realize a lower delay.
