M.Sc. Topic / Guided Research: Ubiquitous Visible Light Communication

Visible light communication (VLC) has been enabling many applications related to IoT, such as accurate indoor localization, gesture recognition, activity detection, occupation detection. A limitation is the coverage of end-user devices which are capable to decode the information transmitted via visible light. For example, personal computers lack of hardware capabilities and other devices such as smartphones, tablets, or laptops are limited in terms of real-time processing. Thus, end-user devices need for VLC additional hardware, such as openVLC [1] or Pulsar [2] which limit the user's mobility. The goal of our work is to shrink the VLC receiver to an appropriate size for everyday usage towards ubiquitous VLC. Thereby, the created VLC sticker can be easily attached to different end-user devices or objects to receive the VLC-transmitted data. The VLC sticker should work completely passive, for operation the required energy is induced by a solar panel. The light source acts as energy source and at the same time as data transmission medium. We use NFC as interface to the end-user devices. The data flow is as follows: light source as active transmitter, the VLC sticker receives and process the information in real-time and finally streams it via NFC to the end-user device.
