Special Issue Information
Dear Colleagues,
There can be little doubt that video traffic accounts for a very large, and ever-growing proportion of all traffic in mobile networks. Nevertheless, as we slowly transition to operational fifth generation (5G) mobile networks and researchers explore further innovation beyond 5G, many challenges remain.
While much researched, the question of how to ensure quality of experience for nomadic consumers of streamed video content remains open and topical. However, 5G networks are anticipated to support a much wider range of video-based services than their predecessors, and many of these services, such as telemedicine or remote surgery, will place very onerous bi-directional latency and reliability constraints on the delivery mechanisms.
The 5G network architecture, and its use of network function virtualisation and software defined networks, may permit the timely deployment of video-related services at the network edge in response to demand or certain operational requirements. For example, content delivery networks could dynamically reconfigure themselves by placing new caching servers at edge nodes or public safety and security monitoring systems could deploy local processing (e.g., facial recognition) at network edges in certain situations.
Recent developments in video encoding mean that there are now new codecs such as H.266 that offer very efficient video compression but with a significant processing overhead. The introduction of such codecs in mobile environments will have an impact of the level of video traffic traversing mobile networks.
This Special Issue aims to bring together the latest research on video encoding, transcoding, and transmission in current and future mobile networks. Topics of interest include but are not limited to the following:
- Quality of experience in mobile networks;
- Dynamic reconfiguration of content delivery networks;
- Novel video-related services for evolving network environments;
- In network transcoding/decoding or reencoding of video content to accommodate new codecs such as H.266;
- New models for public safety monitoring that leverage the network edge to distribute and improve processing;
- In-network adaptation of video flows in response to changing mobile network conditions.

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. Future Internet 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 1600 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.
