Special Issue Information
Dear Colleagues,
The constantly increasing need for data exchange among various types of devices, mobile and fixed, has been one of the main characteristics of the technological development of the last few years. Wireless networking is booming thanks to the rapid progress of wireless technologies and the adoption of broadband. Applications with 5G already include a wide range of radio devices to enable control, monitoring, and easy configuration. Most of these devices operate in the ISM bands, which are becoming increasingly congested, leading to capacity and interference limitations.
Recent technical advances in the areas of cognitive radio (CR) and wideband transceivers have enabled the reutilisation of the available spectrum in a dynamic manner, but there are still several important challenges to be addressed. On the one hand, there are technical issues in dealing with several practical criticalities such as noise, interference uncertainty, and synchronization issues. On the other hand, there are several regulatory and business challenges for dynamic spectrum access in 5G networks.
In this context, CR systems—employing technologies aware of the operational and geographical environment, policies and internal state—can dynamically and autonomously adjust their operational parameters and protocols according to the obtained knowledge in order to deal with the specific challenges of 5G networks.
The topics of interest include, but are not limited to:
- Spectrum regulation and management aspects for CR communications in the 5G era
- Energy and spectral efficiency
- Software defined networks (SDN) and software defined radio (SDR) for CR communications in the 5G era
- CR standardization
- Interference and power control
- Radio resource allocation and scheduling
- CR non-orthogonal multiple access (NOMA) frameworks
- CR for device-to-device (D2D) communications in the 5G era
- CR for V2V and V2X communications in the 5G era
- CR in 5G networks
- CR for IoT
- CR for social networking
- CR trials, test-beds, prototypes, and implementations
- Security and privacy for CR communications in the 5G era

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.
