Underwater Optical Wireless Communications

Dear Colleagues,

In scientific, military, and industrial sectors, the development of robust and efficient submarine wireless communication links is of enormous interest. Underwater optical wireless communication (UOWC) has recently emerged as a unique opportunity for high-data-rate and moderate-distance communication in the undersea environment. Several applications with a large amount of data such as real-time video transmission and the control of remotely operated vehicles could greatly benefit from UOWC. The purpose of this Special Issue is to focus the attention on specific areas that need further enquiry in order to continue to develop this important sector of wireless communication. Many studies are available in the literature. Unfortunately, most of them are conducted by simulation or by laboratory experiments. Studies in real marine environments are needed.

The aim of this Special Issue is to encourage studies on underwater optical wireless communication in terms of interface platforms, applications, and regions.

In particular, the intention of this Special Issue is to encourage research on

• The development of new models of submarine communication channels.
• The development of techniques to limit the impact of misalignment between transmitter and receiver (design of smart transmitters/receivers).
• The design of innovative modulation and coding schemes capable of adapting the transmission characteristics in the underwater environment.
• Designing UWOC with optimized energy efficiency.
• The possibility of using differently colored light sources at the same time to increase the data transfer speed and/or allow simultaneous use by multiple users.

You are invited to submit your original research papers, in the form of communications, full articles, topic or perspective reviews, including the latest and most original advances regarding the current state-of-the-art in underwater optical wireless communication. Topics may include but are not limited to:

• Emerging underwater communication technology;
• Characterization of aquatic optical channels;
• Optical light sources for UOWC systems;
• Detector sensors for UOWC systems;
• Power consumption;
• Application of single-photon avalanche diode (SPAD) technology to UOWC systems;
• Underwater RF communication;
• Internet of Underwater Things (IoUTs);
• Hybrid underwater acoustic/optic communications;
• Modulating schemes for UOWC systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
