Accuracy indicator for fingerprinting localization systems

Fingerprinting is a technique that records vectors of received power from several transmitters, and later matches these to a new measurement to position the new user. This paper proposes a new mechanism to calculate the (Dilution of Precision) DOP-like value and error estimation for fingerprinting localization by investigating relationship between real distance and “vector” distance between fingerprints used in earlier fingerprinting experiments in Wi-Fi and FM radio networks. However, because fingerprinting algorithms use nearest neighbor techniques, the relationship between real distance and “vector” distance of these nearby fingerprints was also examined and found to more helpful when estimating the position. The proposed method used only the information from the training stage of fingerprinting and when compared with previous literature, it was found to give the improved results.
