Comprehensive analysis of distance and similarity measures for Wi-Fi fingerprinting indoor positioning systems

作者:

Highlights:

• We introduce a study in depth of distance/similarity measures for indoor location.

• Alternative measures provide better results than commonly used Euclidean distance.

• Choosing an appropriate non-linear representation is crucial for intensity values.

• Very low intensity values are representative and they should not be filtered.

• All the experiments are validated with a public database, so they are reproducible.
