This work proposes a method for edge server selection in radio access networks, assuming high temporal and spatial dynamics of user demands. A method for selecting a server in a named data network using a wireless access point as a broker representing the interests of a mobile user is proposed. A simulation model is implemented in the ndnSIM software environment, which makes it possible to experimentally evaluate the performance of the proposed solutions. Our numerical experiment results demonstrated that proposed solutions are significantly outperformed legacy network architectures in terms of reducing the latency.

Keywords: molecular analysis, NIR spectrometer, Internet of Things, cloud services, edge computing, mHealth.
The article provides an overview of the features of the use of portable general-purpose NIR spectrometers to analyze the composition of food or medicines. A model of the aggregated network traffic flow of several spectrometers and a service delivery model, which provides the reduction of network delay and amount of transmitted data, are presented. A method of constructing a network based on edge computing for reduction of network delay is considered. To verify the proposed model and method simulation modeling was carried out in the software environment AnyLogic.

Keywords: electromagnetic field, mobile phone, risk group, central nervous system, neoplasms, prognosis, health, radiofrequency, exposure, morbidity, children.
The first scientific predictions about the possible impact of the electromagnetic field of mobile phones on human health were made in 1996−2008. Then an increase in the number of cases of malignant neoplasms and non-cancerous diseases of the nervous system was predicted. Now the national medical statistics show trends in the growth of morbidity for certain classes of diseases that were included in the forecasts. Data on the increase in morbidity are most noticeable in the group of children aged 15−17 years.

Keywords: GLONASS, navigation system, surface sea navigation, underwater navigation, underground navigation, Arctic region.
The article presents an overview of consumer navigation equipment designed to solve special problems. The equipment in conditions of rapid development of navigation services is of wide interest to both civil and military customers. The following special tasks are considered: navigation maintenance of construction of complex high-rise and long facilities; surface and underwater navigation of ships, including in the Arctic region; and underground navigation. It is shown that at present the solution of these problems has achieved some success, but there are still unsolved problems that require a quick solution.

The transition to the information society makes us think about the readiness of graduates for life and work in the society of the 21st century. Given that the rate of transformation of production technologies is now ahead of the rate of generational change, it is necessary not only to improve and additional training but also to repeatedly master new types of activities during working life: continuous education becomes an integral part of every person’s life. To simplify the perception of the increasing flow of information at various stages of the educational process, it is necessary to introduce innovative information technologies, one of which can be technical means of intelligent processing of educational content, the quality of which determines the course and outcome of the educational process.
