A Multi-sensor Office-building Database for Experimental Validation and Advanced Control Algorithm Development

Nicolas Morel, Nikolaos Zarkadis

Data from multiple sensors and actuators has been recorded from December 2001 to March 2008 at the LESO-PB building of the EPFL campus, using the EIB/KNX bus standard. Sensors and actuators provided data on room temperature, presence, lighting level, windo ...

Robust Asynchronous Indoor Localization Using Led Lighting

Andreas Peter Burg, Nicholas Alexander Preyss, Georg Robert Kail

We propose a low-cost system for indoor self-localization of mobile devices using modulated LED ceiling lamps that are fully autonomous and broadcast their identifiers without any synchronization. The proposed self-localization method is designed to handle ...
