Technologies for Underwater Wireless Communication

Dear Colleagues,

The exploration of the underwater world has always represented a major goal for researchers and scientists. However, more recently, knowledge of and access to this environment have become a necessity in developing communication infrastructures to support civil, commercial, and military activities.

For many years, the scientific community has been working on underwater communications, not only developing solutions related to hardware and software but also, above all, working to define a framework of technologies and rules to ensure robust connectivity in this very challenging propagation scenario.

Wireless acoustics, magnetic induction, and, more recently, optical communication have represented the research directions of greatest interest. The work carried out in these areas is converging towards the achievement of the so-called Internet of Underwater Things paradigm, in which efficient traffic management will constitute a key challenge. In this regard, machine learning and artificial intelligence are expected to provide crucial support.

This Special Issue will showcase papers introducing novel solutions related to underwater communications. Topics of interest range from signal propagation to networking, including the following areas:

• Modulation, coding, and detection techniques;
• Channel characterization and equalization;
• Medium access control and routing strategies;
• Security in underwater communication;
• Internet of Underwater Things;
• Underwater device and component design.

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 250 words) can be sent to the Editorial Office for assessment.

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. Applied Sciences 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 2400 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.
