Energy-Efficient B5G/6G Ultra-Dense Networks: Challenges and Solutions

Recently, there has been a rapid increase in the number of base stations (BSs) to support the massive amount of mobile data traffic and explosively increasing number of mobile devices in B5G/6G wireless communication systems and next-generation Internet of Things (IoT) networks. BSs may be more densely deployed to support the enormous number of mobile devices. However, there still exist several fundamental challenges for minimizing network energy consumption, detrimental interferences, and frequent handovers. Thus, energy-efficient ultra-dense networks are being proposed to satisfy the various requirements of future wireless communication systems, including energy-efficient transmission/reception design, medium access control, scheduling algorithms, network operation and management, device-to-device communications, uncoordinated and massive random access, hybrid beamforming, massive MIMO, stochastic geometry-based network modeling, energy-efficient fronthaul/backhaul, machine-learning-based network control, UAV-based traffic offloading, UAV-based outage compensation, etc.

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. Electronics 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.
