Optical Wireless Communication for the Internet of Things: Advances, Challenges, and Opportunities

Abstract

<div>The continuous development of the Internet of Things (IoT) calls for innovative solutions and technologies to realize the IoT vision efficiently. One of the rising connectivity technologies that can potentially benefit the IoT deployment is Optical Wireless Communication (OWC) technology. In OWC, light beams from light sources are used to modulate information. The receiver demodulates the received light and processes the signal. The broad unlicensed spectrum of the OWC technology, along with its potential high bit-rate and increased physical link security, motivated researchers to consider OWC for IoT solutions. In this paper, we survey the existing literature related to using OWC technology in the IoT domain. We present the background and preliminaries of the IoT and OWC domains to understand how the OWC fits in the IoT architecture. Then we perform a comprehensive survey of literature related to the use of OWC technology in IoT applications. We highlight and summarize the major papers and experiments in the literature to provide researchers a jump-start to tap into the domain of OWC in IoT using the systemic and detailed survey presented in this paper.</div>

Improving the error performance of offset pulse position modulation using Reed–Solomon error correction code and low-density parity

“…The most significant bit (MSB) has stripped the PCM term and owns 2 m-1 delay time slots by the decoder and OPPM coder. For the first time, PPM was successfully implemented on a visible light communication (VLC) system with a 'warm' 30W LED, reaching a data throughput of 11 Mbps and having zero errors in transmission over a 1 m space that is free [8]. OPPM error causes have been addressed by Wang et al [9] using the automatic repeat request (ARQ) method.…”

LiDAR Integrated High-Capacity IR OWC System with Abilities of Localization and Link Alignment

“…Thus, broadband data communication is highly demanded. However, nowadays widely applied radio frequency spectrum is getting overcrowded and exhausted [2,3]. Optical wireless communication (OWC) technique is a promising solution to solve this issue, which usually works at a higher frequency with a much more broad spectrum.…”
