Special Issue Information
Dear Colleagues,
Future 6G sensor networks will witness a paradigm shift towards heterogeneous devices, massive connections, and ubiquitous distributions towards 2030. In particular, it is expected that 6G networks can realize stringent seamless coverage with nearly 100% geographical areas including oceans, forests, and mountainous areas. Existing terrestrial networks suffer from restricted connectivity, low expandability, and limited spectral efficiency. There is a growing interest in technologies capable of coping with these challenges. Space–air–ground integrated networks (SAGIN) exhibit ubiquitous coverage, all-weather capability, and strong flexibility, which can meet the requirements of future 6G networks. Research on SAGIN needs to cover the design of network topology, physical layer technology, transmission security, etc. This Special Issue of Sensors is aiming at collecting state-of-the-art research papers related to the emerging technologies of 6G SAGIN for future sensor networks. Topics of interest include, but are not limited to, the following:
- Physical-layer technologies design for SAGIN;
- Multiple access technologies for SAGIN;
- Random access technologies for SAGIN;
- Transmission security for SAGIN;
- Routing technologies for SAGIN;
- Machine learning methods in SAGIN;
- Spectrum sensing technologies for SAGIN;
- Network architectures/transmission protocols for SAGIN;
- SAGIN for IoT/IIOT/IoE;
- Sensing/positioning/detection in SAGIN.
Sensors are used to collect interesting data on diversified scenarios, which enable smart cities and other ubiquitous monitoring applications. This Special Issue pays attention to the transmission of the data collected by sensors. In the future, sensor networks are expected to support sensing for ubiquitous areas, especially remote areas that cannot be easily covered by terrestrial networks. SAGIN can effectively realize ubiquitous coverage, massive connection, and robust data transmission. This is particularly attractive for supporting the emerging requirements of the future ubiquitous sensor networks.

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.
