Visible light LEDs, due to their numerous advantages, are expected to become the dominant
indoor lighting technology. These lights can also be switched ON/OFF at high frequency …

This paper proposes Kalman-filter drift removal (DR) and Heron-bilateration location
estimation (LE) to significantly reduce the received signal strength index (RSSI) drift …

Wi-Fi fingerprinting is a well-known technique used for indoor positioning. It relies on a
pattern recognition method that compares the captured operational fingerprint with a set of …

Reliable indoor positioning is an important foundation for emerging indoor location based
services. Most existing indoor positioning proposals rely on a single wireless technology, eg …

Recently, it is believed that lighting and communication technologies are being replaced by
high power LEDs, which are core parts of the visible light communication (VLC) system. In …

Although global positioning system (GPS) has largely solved the problem of outdoor
navigation, indoor positioning systems have remained a challenging problem over the last …

In spatial science and urban applications,“space" is presented by multiple disciplines as a
notion referencing our living environment. Space is used as a general term to help …

A novel indoor positioning algorithm with improved location accuracy is proposed for visible
light communication system. The novelty of the positioning algorithm lies in a hybrid …

Fingerprint is one of the most widely used methods for locating devices in indoor wireless
environments and we have witnessed the emergence of several positioning systems aimed …
