Mathematical model of LoRaWAN channel access with capture effect
P. 1–5.
In press
LoRaWAN is a promising low power long range wireless communications technology for the Internet of Things. An important feature of LoRaWAN gateways is related to so-called capture effect: under some conditions the gateway may correctly receive a frame even if it overlaps with other ones. In this paper, we develop a pioneering mathematical model of a LoRaWAN network which allows finding network capacity and transmission reliability taking into account the capture effect.

BACKGROUND: The “Perceived Ability to Cope with Trauma Scale” (PACT) is designed to assess individuals’ perceptions of their ability to use various coping strategies when facing potentially traumatic events. These include focusing on the cognitive processing of the trauma (the “Trauma Focus” subscale) and overcoming the trauma (the “Forward Focus” subscale). The key advantages of the PACT scale include ...

Nowadays the space sphere is actively developing. Reliability is a fundamental aspect, as its deficiency can have serious consequences: huge material losses, loss of human life as a result of accidents. Thus, the development and production of space systems requires strict control and evaluation of reliability indicators to ensure flight safety and efficient functioning of ...

In modern radio-electronic devices there is a problem of discrepancy between the results of calculated estimation of dependability (failure-free) indices at the design stage and real statistics of failures during operation at the production stage. The difference of failure rates in the case of calculation and statistics is several orders of magnitude. There is also ...

Within-host infection dynamics of Omicron dramatically differs from previous variants of SARS-CoV-2. However, little is still known about which parameters of virus-cell interplay contribute to the observed attenuated replication and pathogenicity of Omicron. Mathematical models, often expressed as systems of differential equations, are frequently employed to study the infection dynamics of various viruses. Adopting such ...
