Underwater and Underground Sensor Networks: Theory, Technology, and Application

Dear Colleagues,

With the advent of 6G wireless systems, non-terrestrial networks (NTNs) have emerged as pivotal components to achieve a seamlessly connected globe. Beyond the well-explored realms of satellite communication, the integration of underwater and underground wireless systems is crucial for a truly interconnected world. These systems, especially underwater and underground sensor networks, are at the forefront of enabling humans to explore and monitor subsurface environments effectively. Despite the distinct wireless technologies employed in underwater and underground settings, these communication and networking systems exhibit significant similarities, largely due to the deployment of wireless sensors in subsurface contexts.

This Special Issue seeks to showcase cutting-edge research and comprehensive reviews of the latest advancements in underwater and underground sensor networks. It focuses on novel theories, technologies, and applications that push the boundaries of what is currently possible. Our objective is to foster an environment where advancements in one area can inspire and accelerate progress in another, leveraging the unique challenges and solutions each domain presents.

We invite contributions on a broad range of topics, including, but not limited to, the following:

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.
