摘要
为了提升可计算射频识别(computational radio frequency identification,CRFID)系统通信性能,提出快速响应方案和数据重传机制。针对CRFID标签响应阅读器速率较慢导致通信失败问题,利用预计算RN16、固定标签句柄方法简化通信过程,提升了标签响应速率;针对CRFID标签数据出错重传方案效率低、能耗大的问题,采用将标签数据和数据地址相结合的数据格式进行传输。阅读器通过出错数据的地址,可精确定位出错数据并重新请求标签数据,提高了大块数据传输成功率,降低出错重传的能耗。最终通过实验验证可知,该方案有效提高了无源CRFID系统通信性能。
In order to improve the communication performance of Computational Radio Frequency Identification(CRFID)system,a fast response scheme and a data retransmission mechanism were proposed.Aiming at the issue of communication failure caused by the slow response rate of CRFID tags to readers,the use of pre-calculated RN16 and fixed tag handle methods simplifies the communication process and improves the response rate of tags.For the issue of low efficiency and high energy consumption of CRFID tag data retransmission,the data format combining tag data and data address is used for transmission.The reader can accurately locate the error data and re-request tag data through the address of the error data,which improves the success rate of bulk data transmission and reduces the energy consumption for retransmiting errors data.Finally,through experimental verification,it can be known that the scheme improves the communication performance of the passive CRFID system.
