A Narrow-Band Indoor Positioning System by Fusing Time and Received Signal Strength via Ensemble Learning

Π8: Indoor Positioning System using WLAN Received Signal Strength Measurements

In this deliverable we provide the details of building an indoor positioning system using WLAN Received Signal Strength (RSS) fingerprints. The positioning system has been deployed at the premises of KIOS Research Center and follows a terminal-based-network-assisted architecture. In our case, users that carry a terminal (Tablet PC) are able to self-locate and positioning is performed entirely o...

Received Signal Strength Database Interpolation by Kriging for a Wi-Fi Indoor Positioning System

The main approach for a Wi-Fi indoor positioning system is based on the received signal strength (RSS) measurements, and the fingerprinting method is utilized to determine the user position by matching the RSS values with the pre-surveyed RSS database. To build a RSS fingerprint database is essential for an RSS based indoor positioning system, and building such a RSS fingerprint database requir...

Received Signal Strength Recovery in Green WLAN Indoor Positioning System Using Singular Value Thresholding

Green WLAN is a promising technique for accessing future indoor Internet services. It is designed not only for high-speed data communication purposes but also for energy efficiency. The basic strategy of green WLAN is that all the access points are not always powered on, but rather work on-demand. Though powering off idle access points does not affect data communication, a serious asymmetric ma...

Learning Indoor Localization using Radio Received Signal Strength

A Robust Received Signal Strength Based Positioning Algorithm for Indoor Environments

Localization for mobile wireless sensor networks has been intensively studied in recent years due to its many applications in mobile networking as well as various public safety problems. However, the complexity of indoor radio propagation, especially when considering mobile users, makes indoor positioning a challenging task. This is mainly due to the severe multipath phenomenon where multiple c...
