A 3D Source Fingerprinting-Based Localization System

A WLAN Fingerprinting Based Indoor Localization Technique

Satellite-based Global Positioning Systems (GPS) have enabled a variety of location-based services such as navigation systems, and become increasingly popular and important in our everyday life. However, GPS does not work well in indoor environments where walls, floors and other construction objects greatly attenuate satellite signals. In this paper, we propose an Indoor Positioning System (IPS...

Fingerprinting based localization in heterogeneous wireless networks

Indoor Localization based on Multipath Fingerprinting

In recent years there has been a growing interest in position location in indoor venues. As more applications requiring indoor localization are emerging in the market, the demand for accurate and reliable localization increases. Unfortunately, the accuracy of available techniques is limited, and a dense and expensive deployment is required. The problem of accurate indoor localization is challen...

Weighted Fingerprinting Localization based on a Multichannel WiFi Map

WiFi localization based on fingerprinting method became popular during last decade. However, collecting information to construct a WiFi signal map is challenging due to high cost. We assume that it is possible to gather such information with cheap cost using crowd sourcing with smartphones. Each user’s current location is estimated by either GPS, WiFi, radio cell signals or manually set by the ...

A Mathematical Model for Fingerprinting-based Localization Algorithms

Despite the popularity of Fingerprinting Localization Algorithms (FPS), general theoretical frameworks for their performance studies have rarely been discussed in the literature. In this work, after setting up an abstract model for the FPS, it is shown that fingerprinting-based localization problem can be cast as a Hypothesis Testing (HT) problem and therefore various results in the HT literatu...
