Abstract

In this paper impact of the Access Points on localization accuracy of Rank Based Fingerprinting algorithm will be investigated. Rank Based Fingerprinting and Nearest Neighbor (NN) family algorithms will be described in detail. Results achieved by this algorithm were compared to NN and WKNN algorithm. Simulations were performed in Matlab environment in two different scenarios. The first scenario was proposed to evaluate impact of APs placement in the localization area. In the second scenario different numbers of APs were implemented in the area to estimate impact of APs number on the localization accuracy of the Rank Based Fingerprinting algorithm.
