Wi-Fi Sensing: Applications and Challenges

Dear Colleagues,

Recently, Wi-Fi sensing is attracting increasing attention as a new innovative sensing technology. Wi-Fi sensing is a technology which uses exiting Wi-Fi signals to perform sensing applications such as motion detection and gesture recognition as well as fine-grained biometric measurement. Compared with traditional approaches, it has a series of advantages and provides a compelling alternative, for instance, in that it does not require lighting, offers better coverage as it can sense through walls, and offers a high level of user privacy. As a result, it provides opportunities for home security, healthcare and service providers within enterprises and many more. This growth in Wi-Fi sensing applications brings forward an inevitable need for more efficient and intelligent processing, implementation and deployment.

While some applications can be enabled using existing standards, however, there is no standard for Wi-Fi sensing and its implementation, limiting the range of what Wi-Fi sensing can do. Consequently, new tools and methods are required to embrace a variety of Wi-Fi sensing applications.

The aim of this Special Issue is to investigate the latest research trends and recent development of new frameworks, mechanisms, and algorithms that are able to support Wi-Fi sensing technology.

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.
