Today art museum is facing the challenge of adapting it’s mechanisms of keeping and presenting the works of art to spectators belonging to the communication society. Therefore, a museum gets more and more engaged in the process of digitalization using such newer technologies as internet of things, virtual reality, artificial intelligence, bid data design etc. The aims of a museum are currently shifting from traditional keeping the art pieces and studying them to—developing a scientific networks, announcing the highlights in social media and creating platforms which present digitalized pieces online allowing a viewer to collect the information through the web, moreover, an offline visit could be guided by a specified application customized to fit the necessitates of each user. An art institution today is supposed to be flexible and democratic enough to create an engaging, immersive area for a visitor to interact with, in other words, we argue that a museum armed with newer technologies is supposed not only a to secure and present the works of art but also to incorporate these pieces into the bigger flux of information, make them visible and important to viewers, to create the conditions for a lasting dialogue. We argue that this process involves not only the technical development of a museum, but also a new approach no narration of art history.

LoRa wireless network has become a widely spread technology among IoT systems recently. LoRa allows to use various ISM bands such as 433 MHz, 868 MHz and 915 MHz. During this study 433 MHz and 868 MHz frequencies have been compared. Parameters such as SNR and RSSI were measured at different floors and visualized. A comparative table of packet delivery ratio at various spreading factors can be found in this paper. A series of range experiments at different spreading factors showed that 433 MHz LoRa module gains a stronger signal. However, 868 MHz LoRa module shows higher percentage of received packets. It has been concluded that for nine-story building with concrete floors it is better to deploy 868 MHz LoRa network at 10th spreading factor.

The paper reviewed and analyzed protocols, technologies for transferring and presenting IoT data, developed a model of a heterogeneous IoT network for hard-to-reach areas, proposed a method to improve the efficiency of data transfer in a heterogeneous IoT network. As a result of the work, a model of using the Internet of Things technology (LPWAN) in hard-to-reach areas was developed, information presentation methods were identified that allow solving the problem of collecting information from remote sensors located in the absence of traditional communication channels and a practical check of the results obtained. The paper uses simulation modeling to study the applicability of different methods of presenting information in the case of transmitting IoT data over low-speed satellite communications channels. The method proposed in the paper allowed the use of the Internet of things technology in remote areas using the SBD satellite short message service. The proposed method allowed reducing the volume and number of SBD messages during data transmission via low-speed satellite communication channels, which made it possible to reduce the cost of communication data transmission by 4.82 times.

In the absence of traditional communication infrastructures, the choice of available technologies for building data collection and control systems in remote areas is very limited. This paper reviews and analyzes protocols and technologies for transferring Internet of Things (IoT) data and presents an architecture for a hybrid IoT-satellite network, which includes a long range (LoRa) low power wide area network (LPWAN) terrestrial network for data collection and an Iridium satellite system for backhaul connectivity. Simulation modelling, together with a specialized experimental stand, allowed us to study the applicability of different methods of information presentation for the case of transmitting IoT data over low-speed satellite communication channels. We proposed a data encoding and packaging scheme called GDEP (Gateway Data Encoding and Packaging). It is based on the combination of data format conversion at the connection points of a heterogeneous network and message packaging. GDEP enabled the reduction of the number of utilized Short Burst Data (SBD) containers and the overall transmitted data size by almost five times.

A review and analysis of existing solutions for creating a system for collecting and converting the energy of HF radiation on the Internet of Things is conducted. We propose our development of a system for collecting and converting the energy of HF radiation on the Internet of Things. The result is a proprietary development of a system for collecting and converting high-frequency radiation energy, ready to work at a distance of no more than 0.94 meters from the Wi-Fi router according to the IEEE 802.11 standard. The output voltage in case of continuous operation of our harvester is 3.3 V, which is enough for power supply: temperature sensors with digital output, humidity sensors, and atmospheric pressure sensors. It is possible to achieve an increase in the working distance by increasing the power of the source of electromagnetic waves, to improve the gain of the transmitting and receiving antenna, or to increase the number of receiving antennas.

The problem of energy saving of a mobile device is still relevant, moreover, the need for energy saving increases every year with the advent of the Internet of things. However, despite the significance and effectiveness of previous studies, we still do not know the exact amount of energy consumed by the elements of the mobile device interface. In this regard, our contribution to this study is that we received a specific amount of energy in the established units of measurement consumed by the basic elements of the interface and the main color palette on TFT displays. The data obtained in this study were obtained through many experiments and have some small error associated with the used measurement sensors built into the mobile device. This error was calculated and determined for each element. In addition, the data on the energy consumption of the mobile device were evaluated from a theoretical point of view and a mathematical model of the battery consumption of the mobile device was compiled.

Artificial intelligence technologies are beginning to be actively used in human life, this is facilitated by the appearance and wide dissemination of the Internet of Things (IoT). Autonomous devices are becoming smarter in their way to interact with both a human and themselves. New capacities lead to creation of various systems for integration of smart things into Social Networks of the Internet of Things. One of the relevant trends in artificial intelligence is the technology of recognizing the natural language of a human. New insights in this topic can lead to new means of natural human-machine interaction, in which the machine would learn how to understand human's language, adjusting and interacting in it. One of such tools is voice assistant, which can be integrated into many other intelligent systems. In this paper, the principles of the functioning of voice assistants are described, its main shortcomings and limitations are given. The method of creating a local voice assistant without using cloud services is described, which allows to significantly expand the applicability of such devices in the future.

It is revealed that such radical transformations lead to a change in the formats of cultural objects, their content and form. The prospects of technological development are analyzed and the framework of interdisciplinary research is set.

Considering two main trends in the field of culture - the fusion of art with science and the high demand for viewers’ participation in art-projects, we emphasize the role of technology in the development of media and focus on the prospects that can provide the Internet of things. In addition, analyzing the perspectives of contemporary technological tools as creative tools, we argue that the Internet of things and derivative technologies can have a strong influence on design, education and culture: today the society faces exponential innovative growth in all areas, but the most promising among them are those which provide the user with an active position, ability to provide feedback and an option to become co-author of the responsive, recipient-oriented projects that engage complex technical excellence in order to meet the expectations of a contemporary adaptive user, viewer or student.
