Performance Evaluation of Channel Access in NB-Fi Networks
Journal of Communications Technology and Electronics. 2022. Vol. 67. No. 6. P. 747–754.
The rapid growth of the Internet of Things gives rise to numerous Low Power Wide Area Network technologies, one of which, NB-Fi technology, has been approved as a Preliminary National Standard of the Russian Federation and is planned for wide application. However, the scientific literature contains very few studies of NB-Fi, and the investigation of the possibilities and potential advantages and disadvantages of NB-Fi is an open issue. This paper provides a tutorial of the NB-Fi protocol with a focus on channel access methods. Also, the paper evaluates how the packet loss rate and delay depend on the network load, points out the factors that can reduce the protocol efficiency, and proposes some approaches to improve the NB-Fi network performance.

Comprehensive data on natural hazards and their consequences are crucial for effective for risk assessment, adaptation planning, and emergency response. However, many countries face challenges with fragmented, inconsistent, and inaccessible data, particularly regarding local-scale events. To address this data gap in Russia, we developed an end-to-end processing pipeline that scrapes news from various online sources, ...

During magnetospheric perturbations a relatively thin current sheet with thickness about several
proton gyroradii forms in the Earth’s magnetotail. In a framework of the kinetic model describing current
sheet thinning in the magnetotail, the processes of its formation are investigated depending on the normal
magnetic field magnitude which affects both the current sheet structure and particle dynamics within ...

The influence of asymmetry of plasma sources on the structure and spatial localization of a superthin
current sheet (STCS) supported by demagnetized electrons is studied using a self-consistent model. The
simulation takes into account the presence of a single plasma source in the northern hemisphere, which
makes the plasma flow asymmetric. It is demonstrated that the asymmetry of ...

A model of the cathode layer of a glow gas discharge with a thin dielectric film on a fraction of the
cathode’s working surface is formulated. It is shown that a glow discharge most rapidly transits to an arc discharge,
accompanied by a significant increase in discharge current density and a decrease in cathode voltage
drop, if the ...
