基于仲裁集的RFID主动式标签防碰撞MCMA协议

摘要

Based on the concept of the quorum system, aimming at an active tag's condition, a multi-channel anti-collision protocol MCMA of radio frequency Identification ( RFID) is proposed. Through making full use of the multiple channel to reduce the probability of the collision, thereby the throughput of the whole network is increased as well as the electricity comsuming is reduced. The simulation results show that the protocol can reduce the probability of the collision efficiently and be more economical to work around at the initiative tag condition. As a result, the entire efficiency of FRID system is improved.%基于仲裁集的概念,针对主动式标签环境提出一种多频道RFID防碰撞协议MCMA,以达到充分使用多频道资源来降低碰撞概率,进而增加整个网络的吞吐量,并减少标签的耗电量.仿真结果显示该协议能有效减少碰撞、降低能耗且适用于RFID系统下主动式标签的环境,进而提升RFID系统整体识别效能.
