One of the most promising modalities for this purpose is WiFi, as it works both indoors and outdoors, and as WiFi signal environment tends to contain significant spatial variation.
To overcome these limitations, we propose the cluster k-nearest neighbor (KNN) algorithm with 5 G WiFi signal to reduce the environmental interference and improve the localization performance without additional equipment.
It is novel in that it removes the WiFi association overhead using the beacon stuffed WiFi communication and also provides an efficient collision estimation algorithm to issue appropriate warnings.
WiFi positioning techniques based on signal angle-of-arrival measurements have good accuracy and are promising.
In fact, the more friendly the building to WiFi signal, the more efficient the 802.11 based wireless infrastructure.
In this study, we propose two accurate approaches using only received signal strength (RSS) measurements from WiFi signals to identify NLOS conditions and mitigate the effects.
