This paper introduces a review article on indoor localization techniques and technologies.
The paper starts with current localization systems and summarizes comparisons between …

This paper provides an overview of the most significant existing methods for indoor
positioning on a contemporary smartphone. The approaches include Wi-Fi and Bluetooth …

This article proposes recurrent neural networks (RNNs) for the WiFi fingerprinting indoor
localization. Instead of locating a mobile user's position one at a time as in the cases of …

The advent of the Internet of Things has witnessed tremendous success in the application of
wireless sensor networks and ubiquitous computing for diverse smart-based applications …

The term “ranging” is often used to indicate the operations that make it possible to estimate
the distance between two nodes by processing some signals generated and/or received by …

Outdoor positioning systems based on the Global Navigation Satellite System have several
shortcomings that have deemed their use for indoor positioning impractical. Location …

This paper proposes a soft range limited K-nearest neighbors (SRL-KNNs) localization
fingerprinting algorithm. The conventional KNN determines the neighbors of a user by …

Radio frequency (RF) based wireless power transfer provides an attractive solution to
extend the lifetime of power-constrained wireless sensor networks. Through harvesting RF …

Wi-Fi based fingerprinting systems, mostly utilize the Received Signal Strength Indicator
(RSSI), which is known to be unreliable due to environmental and hardware effects. In this …

LTE-Licensed Assisted Access (LAA) networks are beginning to be deployed widely in
major metropolitan areas in the US in the unlicensed 5 GHz bands, which have existing …
