Cover Story: Recent advances in semiconductor and light devices have triggered remarkable research interest to the development of these optical wireless communication (OWC) links: free-space optical (FSO) links, ultraviolet links that operate within the (UV-C) spectral band, and transdermal optical wireless (TOW) links. In the current review, a background on the energy efficiency challenges in wireless communication is presented. Each of these OWC technologies is mainly discussed in terms of key energy consumption requirements and major limiting factors that affect their power performance. Energy-efficient modulation formats as well as other powerful techniques for performance enhancement such as diversity and relaying are assessed. The survey is concluded with a discussion regarding their future energy consumption requirements and trends. View this paper
