Special Issue Information

Dear Colleagues,

We can announce the third instalment of the Special Issue series on “Underwater Acoustic Communication and Networks”. In the first two instalments, 17 high-quality papers were accepted and published. Given recent developments and the rapidly growing interest in marine robotic networks, the third Special Issue in the series has been titled "Underwater Acoustic Communication and Marine Robot Networks". Marine robots are increasingly being used to carry out varied activities on the sea surface and underwater, such as seabed surveys, water column assessments, offshore infrastructure inspection, marine habitat monitoring, etc. Underwater acoustic communication systems are integral to the operation of marine robot networks. Therefore, seamless operation between acoustic communication systems and marine robots is required.

High-quality papers are encouraged for publication, particularly those directly related to the various topics mentioned below. Furthermore, studies on the development of related novel techniques employed in these research topics are encouraged. Potential topics include the following:

  • Marine robotic systems and networks;
  • Autonomous navigation systems;
  • Underwater sensing;
  • Underwater acoustic communication and networks;
  • Direct to satellite sensor data transmission;
  • Channel estimation and equalisation;
  • Signal modulation and demodulation;
  • Encoding and decoding;
  • MAC and routing protocol;
  • Ad hoc networks;
  • Acoustic modem design and implementation;
  • Underwater unmanned platforms and observatories;
  • Simulation and experimentation;
  • Deep learning-driven underwater acoustic communication;
  • Big data;
  • Machine learning and artificial intelligence.

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. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly 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.

Time synchronization is a crucial element of cooperativity among underwater acoustic sensor networks (UWASNs), and it plays an indispensable role in the application of and research into UWASNs. Although plenty of previous studies on time synchronization for UWASNs have been proposed and applied, most of them cannot perform well when the nodes have high mobility, and they are characterized by low energy efficiency. Tri-Message is a scheme proposed for networks in high-latency and resource-constrained environments, but it works unsatisfactorily when the nodes are movable. In that case, there is no such scheme for high-speed UWASNs with low energy consumption. Herein, we propose LT-Sync, a lightweight time synchronization scheme for high-speed mobile UWASNs. This adopts a Doppler-shift-estimating method to derive the propagation delay of high-speed UWASNs when the unsynchronized node moves uniformly in a single direction. In addition, an underwater spread-spectrum method is adopted for signal receiving to obtain the accurate Doppler shift. The simulation results show that LT-Sync is more feasible for high-speed UWASNs compared to existing methods and has high energy efficiency. Full article
