This paper discusses the effects of random sea surface and turbulence on the performance of underwater optical wireless communication systems (UOWC). Subcarrier intensity modulation (SIM) is presented as a turbulence resilient modulation technique for UOWC. An underwater channel emulator is used to compare the performance of SIM with different modulation techniques. This work demonstrates the feasibility of UOWC with Gbps transmission rates even in the presence of turbulence.

Visible Light Communication (VLC) provides both illumination and communication thanks to the usage of Light-Emitting Diodes (LEDs). In order to support the research in the field, the study of possible infrastructures to enable constant illumination and reliable communication becomes a necessity to pair up the evolution of both fields. Leveraging the fact that LEDs are getting more densely deployed to provide uniform illumination, in this work we present the design of a multi-cell deployment that uses several LEDs as VLC Access Points (APs) for Internet of Things (IoT) applications. We characterize the light emitted by the selected LED and show how this deployment complies with the illumination standards, as well as providing a reliable communication network. We present our design choices for controlling and communicating to the network of VLC APs, and show the required functionalities that must be fulfilled such as power monitoring, power management, and communication management.

As the Visible Light Communications (VLC) is growing up, it is not restricted anymore to the traditional indoor applications such as LiFi or positioning, but it finds new customers at outdoor vendors like underwater and vehicle applications. In this paper we looked at VLC challenges in Vehicular Communications from Medium Access Control point of view. We proposed Link Adaptive Protocol where a single handshake association and fast handover algorithms prolong VLC connectivity. Moreover, adaptive modulation has been suggested in order to increase the throughput. Simulation results show the link adaptive protocol outperforms slotted-aloha in outage probability and goodput, properly achieving a trade-off between pilot rate and protocol efficiency.

This paper positions the idea of enhancing the sensing capabilitiesof unmanned aerial vehicles (UAV or Drones) using LED-Cameracommunication, camera perception, and adaptive sampling algo-rithms. In this paper, considering soil moisture measurement overa specific geographic area as the application, we propose a systemthat consists of drone assisted mobile ground robots(MGRs) thatperform collaborative sensing and communicate with the droneusing visible light. The key idea is to combine aerial images andMGR sensed moisture values to generate a dynamically adaptablemoisture map. Camera communication eliminates the need to estab-lish continuous radio communication in remote locations and offersvisual association that enables the drone to localize the MGRs. Thissystem pushes the state-of-the-art in sensing by accurately sensinga region with high spatio-temporal resolution while optimizing thetime and energy required to create a moisture map of a geographi-cal area. As the sensing resolution is dynamic, we hypothesize thatthe proposed system can efficiently predict, detect, and map soilmoisture hotspots.

A novel adaptive Wavelength Division Multiple Access (WDMA) scheme is presented in this paper, capable of contrasting the effect of the Passband Shift (PS) phenomenon in an indoor densely deployed LiFi network. After an overview on WDMA in an indoor Internet of Things (IoT) setting, simulation work is defined and carried out. Results show how in such settings, the loss of connection is reduced to an average of 0.72 % compared to 31.25 % when using Adaptive WDMA. Additionally, the users are served with higher average speeds and better fairness.

Visible light communication (VLC) is an emerging short-range wireless communication technology using the unlicensed light spectrum. Light Emitting Diode (LED) is used as VLC transmitter, while photodiodes or image sensors are used as receiver, depending on the applications and hardware constraints. However, LEDs can be used not only as a transmitter, but also as a receiver in applications where cost is of primary concern. LED as a receiver is sensitive to a narrow band of wavelengths, it is robust to sunlight interference and widely available as compared to other light detectors. This paper surveys the potential and limitations of LED-to-LED communication. It also contributes to identifying the challenges and potential research directions in this rising area of interest.
