%X Device-to-device (D2D) communication is considered a
promising technique to provide wireless peer-to-peer communication
services. Due to increasing demand on mobile services, available
spectrum for radio frequency (RF) based communications becomes
scarce. Recently, visible light communications (VLC) has evolved
as a high speed wireless data transmission technology for indoor
environments with abundant available bandwidth. In this paper,
a novel VLC based D2D communication that provides wireless
peer-to-peer communication is proposed. Potential low operating
power devices for an efficient D2D communication over increasing
distance of separation between devices is analyzed. Optical repeaters
(OR) are also proposed to enhance the performance in an environment
where direct D2D communications yield degraded performance.
Simulation results show that VLC plays an important role in
providing efficient D2D communication up to a distance of 1 m
between devices. It is also found that the OR significantly improves
the coverage distance up to 3.5 m.
