【摘要】：在被动式RFID系统中,当多个标签同时向阅读器发射信号时,捕获效应能使阅读器成功接收其中一个标签信号。为提高捕获效应下的识别效率,本文提出一种名为CATPE(capture-aware and tag-population estimation)的RFID标签防冲突协议。该协议可同时估计标签数和捕获效应的发生概率,并在非等长时隙下设置最优帧长。CATPE协议的优点在于不需搜索极值,仅一步计算就能完成估计,从而降低了计算复杂度。计算机仿真显示,该协议与已有协议的识别效率相近,但计算复杂度得到了降低。
[Abstract]:In a passive RFID system, when multiple tags simultaneously transmit signals to the reader, the capture effect enables the reader to receive one of the tag signals successfully. In order to improve the efficiency of identification under capture effect, this paper proposes an anti-collision protocol for RFID tags called CATPEcapture-aware and tag-population estimation. The protocol can simultaneously estimate the number of tags and the probability of the capture effect, and the advantage of setting the optimal frame length. CATPE in non-equal time slots is that the estimation can be completed in one step without searching the extremum, thus reducing the computational complexity. Computer simulation shows that the recognition efficiency of the proposed protocol is similar to that of the existing protocol, but the computational complexity is reduced.
