An RFID Indoor Positioning Algorithm Based on Bayesian Probability and K-Nearest Neighbor

open access: yesSensors, 2017
The Global Positioning System (GPS) is widely used in outdoor environmental positioning. However, GPS cannot support indoor positioning because there is no signal for positioning in an indoor environment. Nowadays, there are many situations which require

WLocator: An Indoor Positioning System [PDF]

open access: yesThird IEEE International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob 2007), 2007
There exists a multitude of location-sensing systems utilizing wireless technology, though varying in cost, coverage and accuracy. In this paper we will introduce WLocator, a system that aims to strike a balance between these areas. WLocator will provide location information relative to symbolic, user-created "landmarks".
