A Reliable Localization Algorithm Based on Grid Coding and Multi-Layer Perceptron

open access: yesIEEE Access, 2020
The traditional RSS-based fingerprint localization algorithm needs RSS values from all access points (AP) at each reference point (RP). In the large-scale indoor environment, the increasing of the number of APs will lead to establish a large-scale ...
