Theoretical entropy assessment of fingerprint-based Wi-Fi localization accuracy

作者:

Highlights:

• The entropy is employed as a new metric to evaluate the fingerprint-based Wi-Fi location accuracy.

• The relations of entropy and accuracy with variable RP densities and standard deviations are given.

• The reckless increase of the number of APs cannot be an effective way to improve location accuracy.

• The substantial saving of computation cost by the entropy is achieved over the existing metrics.
