In the near future, with the development of 5G NR, a massive number of IoT nodes are expected to come online. Acquiring bandwidth from an overcrowded licensed radio frequency spectrum as well as overcoming battery life constraints will become the mai

The light-based Internet of things (LIoT) concept defines nodes that exploit light to (a) power up their operation by harvesting light energy and (b) provide full-duplex wireless connectivity. In this paper, we explore the LIoT concept by designing,

The concept of interactive visible light communications (iVLC) is introduced and discussed in this paper. iVLC exploits a matrix of solid-state light luminaries in multiple ways, namely providing lighting and wireless communications as well as suppor
