Résumé:
This paper presents a comparison study of different
similarity metrics used for RSSI fingerprint based indoor localization.
These metrics are used for nearest neighbor search which
is a crucial step in fingerprint localization system. Including
Euclidean distance, Manhattan distance and Gauss distance,
the present study compares the localization error respect to a
proposed parameter named “error densityâ€. This latter is related
to the location error and the size of the studied area. In addition,
different methods of combining the locations of neighbors have
been introduced to estimate the current position and their
performances have been compared. Extensive implementation
details are discussed and simulation is conducted to compare
them. Obtained results show that the Kernel method combined
with the weighted average exhibits the localization accuracy on
the studied dataset.
