论文摘要

尽管RF指纹是本地化最常用的技术之一,但以无处不在的方式部署它,需要解决支持大量异质设备及其变化的挑战。我们提出了QHFP,这是一种与设备无关的量子指纹匹配算法,该算法解决了实现全球无处不在的大型大规模位置跟踪系统的两个问题:存储空间和运行时间以及设备的异质性。特别是,我们提出了一种量子算法,其复杂性在空间和运行时间上都比经典技术好。 QHFP还具有处理固有的本地化误差的规定,原因是使用异质设备构建大型指纹。我们从RAW RSS中提取独立于设备的特征,将经典特征向量映射到其量子对应器的详细信息,并显示量子余弦相似性算法的指纹匹配。 我们已经实现了量子算法,并使用IBM量子机模拟器将其部署在真实的测试台中。结果证实了QHFP获得正确的估计位置的能力,与传统的经典同行相比,空间和运行时间的指数改善。此外,所提出的与设备无关的功能导致中位误差的准确性超过20%。这凸显了我们算法对未来无处不在的全球范围内无独立的指纹定位系统的希望。

Although RF fingerprinting is one of the most commonly used techniques for localization, deploying it in a ubiquitous manner requires addressing the challenge of supporting a large number of heterogeneous devices and their variations. We present QHFP, a device-independent quantum fingerprint matching algorithm that addresses two of the issues for realizing worldwide ubiquitous large-scale location tracking systems: storage space and running time as well as devices heterogeneity. In particular, we present a quantum algorithm with a complexity that is exponentially better than the classical techniques, both in space and running time. QHFP also has provisions for handling the inherent localization error due to building the large-scale fingerprint using heterogeneous devices. We give the details of the entire system starting from extracting device-independent features from the raw RSS, mapping the classical feature vectors to their quantum counterparts, and showing a quantum cosine similarity algorithm for fingerprint matching. We have implemented our quantum algorithm and deployed it in a real testbed using the IBM Quantum machine simulator. Results confirm the ability of QHFP to obtain the correct estimated location with an exponential improvement in space and running time compared to the traditional classical counterparts. In addition, the proposed device-independent features lead to more than 20% better accuracy in median error. This highlights the promise of our algorithm for future ubiquitous large-scale worldwide device-independent fingerprinting localization systems.
