摘要:

基于接收信号强度(RSS)的指纹定位由于其低成本和易于实现而吸引了大量的研究工作,并培养了许多基于位置服务的商业应用。许多研究正在探索使用深度学习(DL)算法进行定位。DL的能力,提取特征和自主分类,使其成为一个有吸引力的解决方案,基于指纹的定位。这些解决方案需要频繁地重新训练具有大量测量的DL模型。虽然众包是收集大量数据的一种很好的方式,但它会危及参与者的隐私,因为它需要在一个集中的服务器上收集标记的数据。最近,联邦学习已经成为一个实用的概念,通过以分散的方式在边缘设备上执行模型训练来解决众包参与者的隐私保护问题;参与者不再将他们的数据暴露给集中式服务器。本文提出了一种新的方法,利用联邦学习,以提高基于RSS指纹定位的准确性,同时保护众包参与者的隐私。采用联邦学习可以确保\emph{preserving the privacy of user data},同时利用在真实环境中捕获的实验数据实现足够的本地化性能。该方法在作为集中式学习的助推器时将定位精度提高了1.8米,并且在独立使用时获得了令人满意的定位精度。

英文摘要:

Received Signal Strength (RSS) fingerprint-based localization has attracted a lot of research effort and cultivated many commercial applications of location-based services due to its low cost and ease of implementation. Many studies are exploring the use of deep learning (DL) algorithms for localization. DL's ability to extract features and to classify autonomously makes it an attractive solution for fingerprint-based localization. These solutions require frequent retraining of DL models with vast amounts of measurements. Although crowdsourcing is an excellent way to gather immense amounts of data, it jeopardizes the privacy of participants, as it requires to collect labeled data at a centralized server. Recently, federated learning has emerged as a practical concept in solving the privacy preservation issue of crowdsourcing participants by performing model training at the edge devices in a decentralized manner; the participants do not expose their data anymore to a centralized server. This paper presents a novel method utilizing federated learning to improve the accuracy of RSS fingerprint-based localization while preserving the privacy of the crowdsourcing participants. Employing federated learning allows ensuring \emph{preserving the privacy of user data} while enabling an adequate localization performance with experimental data captured in real-world settings. The proposed method improved localization accuracy by 1.8 meters when used as a booster for centralized learning and achieved satisfactory localization accuracy when used standalone.
