“…6, which can improve the spectral efficiency further while realizing the flexible dimming with high or low precision demands [15] . Meanwhile, according to the characteristics of visible light channel, the path loss will keep increasing rapidly with the increase of the relative distance and angle of the transceivers, so the receiving performance of mobile users will be much worse compared with that of fixed users [16] . It means that the tolerance of IoL to the mobility of users will increase with the improvement of lighting uniformity, which is also an important part of illumination requirements.…”

Intelligent lighting has attracted lots of research interests to investigate all the possible schemes to support this need as human has spent more and more time indoor. Semiconductor-based illumination network is an ideal bearer to carry on this mission. In this paper, we propose the concept of Internet of Light (IoL) and define its key functionalities by introducing the information and communication technologies to the illumination networks. Our latest research progress on high-speed transmission, resource optimization, and light stroboscopic irradiation experiment based on IoL platform show that IoL can not only provide value-added services such as positioning and information transmission but also act like a sensor network as part of Internet of Things infrastructure. It confirms that with sensors for different purposes integrated into the lamp, IoL helps people be aware of the environmental changes and make the adjustment accordingly, can provide cost-effective information service for Internet of Things applications, and supports the non-intrusive optical therapy in the future.

“…The work in [10] only considered the illumination constraint, the power efficient LED placement problem was formulated as a linear program problem and was thus solved efficiently. While interesting, in [4][5][6][7][8][9][10][11], the interactions between LEDs are not considered, which can significantly affect the signal-to-noise ratio (SNR) at the receiver, thus further altering the optimal indoor LED placement.…”

This paper proposes a novel power-efficient light-emitting diode (LED) placement algorithm for indoor visible light communication (VLC). In the considered model, the LEDs can be designedly placed for high power efficiency while satisfying the indoor communication and illumination requirements. This design problem is formulated as a power minimization problem under both communication and illumination level constraints. Due to the interactions among LEDs and the illumination uniformity constraint, the formulated problem is complex and non-convex. To solve the problem, we first transform the complex uniformity constraint into a series of linear constraints. Then an iterative algorithm is proposed to decouple the interactions among LEDs and transforms the original problem into a series of convex sub-problems. Then, we use Lagrange dual method to solve the sub-problem and obtain a convergent solution of the original problem. Simulation results show that the proposed LED placement algorithm can harvest 22.86% power consumption gain when compared with the baseline scheme with centrally placed LEDs.
