wireless local area networks indoor localization fingerprinting device diversity transfer learning correlation alignment
To solve the problem of variations in radio frequency characteristics among different devices, transfer learning is applied to transform device diversity to domain adaptation in the indoor localization algorithm. A robust indoor localization algorithm based on the aligned fingerprints and ensemble learning called correlation alignment for localization(CALoc)is proposed with low computational complexity. The second-order statistical properties of fingerprints in the offline and online phase are needed to be aligned. The real-time online calibration method mitigates the impact of device heterogeneity largely. Without any time-consuming deep learning retraining process, CALoc online only needs 0.11 s. The effectiveness and efficiency of CALoc are verified by realistic experiments. The results show that compared to the traditional algorithms, a significant performance gain is achieved and that it achieves better positioning accuracy with a 19% improvement.
