Effect of distance metrics on positioning accuracy [Uzaklik metriklerinin konumlama başarimina etkisi]
Altın, U. C.; At, Nuray; Topal, C. (Institute of Electrical and Electronics Engineers Inc., 2018)RF fingerprinting based positioning systems have come to the forefront among indoor positioning systems as they provide both high precision and can use existing infrastructure like Wi-Fi access points effectively. In this ... -
Effectiveness of online RF fingerprinting for indoor localization
Othman, H.; At, Nuray; Topal, C. (Institute of Electrical and Electronics Engineers Inc., 2018)This paper proposes a method for indoor localization by introducing an online Radio Frequency (RF) fingerprinting approach instead of the traditional offline RF fingerprinting. The offline phase is a time-consuming stage ... -
