DynamicVLBC: Battery-less Visible Light Backscatter Communication in Dynamic Conditions

Visible Light Communication (VLC) has been gaining interest in the industry and academia for the last decade. VLC enables a high-speed communication alternative to conventional radio such as Bluetooth or WiFi and presents a solution to the 'spectrum crunch'. More recently, the combination of energy harvesting and VLC has been explored to enable...

Indoor Multi-Target Tracking with Solar Cells

Solar cells are usually used as power source, but can be used for sensing as well. We propose a novel indoor tracking system that tracks people by using the change in output caused by their shadows. First, we develop a simulator to determine how the solar cells should be positioned in the tracking environment to get the best detection rate. This...
