Combining smart lighting and radio fingerprinting for improved indoor localization

This work proposes a hybrid indoor positioning system, which combines a minimal smart lighting deployment for Visible Light Positioning (VPL) purposes, with an IEEE 802.11 RSS Fingerprint-based Indoor Positioning System. Such a hybrid deployment improves the localization performance by utilizing the benefits of both the visible light and radio technologies. Improvement is demonstrated in terms of accuracy, coverage and processing requirements. At the same time, the deployment cost and complexity remains in affordable levels, due to the minimal deployment of the smart lighting system and the utilization of an existing IEEE 802.11 wireless network.
