DECODING OF MAXIMUM LENGTH CODES BY K-ELEMENT LINEARLY INDEPENDENT COMBINATIONS USING SOFT SOLUTIONS
S. Vladimirov, D. Mukhametshina
Abstract: Research subject. The article is devoted to the maximum length codes method of soft decoding based on the method of decoding using k-ary linearly independent subsequences. Method. The principle of decoding by k-ary linearly independent subsequences using soft solutions based on weight patterns is considered. The analysis of decoding errors of different weight is performed. Core results. A table of weight patterns for the maximum length code (15, 4) was obtained. Scenarios for the use of the proposed decoding method have been developed. Practical relevance. The developed soft decision based decoding method can be used in a demodulator–decoder bundle to correct errors in codewords and to assess the quality of a data transmission channel based on the error rate in the resulting code combination.
Keywords: maximum length code, soft decoding, M-sequence, decoding by linearly independent subsequences.

OVERLAY NETWORKS MODELS
V. Elagin, Y. Dmitrieva
Abstract: Research subject. This article discusses the effect of the size of a TCP window on the numerical characteristics of the intervals between packets: the initial moments of the intervals from the first to the third, since the developed mathematical model uses the first three starting points. Method. The researches were carried out on a virtual experimental installation, which is deployed using the OpenNebula platform on physical servers. Two cases are considered: a software-configured network with Open-Flow open protocol and a traditional network without the OpenFlow protocol. The software configurable network is built with a POX controller and a physical OpenFlow switch. The tcpdump software used to capture traffic and Iperf to generate traffic are used as tools. Core results. The results obtained are imported into MS Excel and using the known formulas of mathematical statistics, the moment characteristics of time intervals are determined. Practical relevance. Thanks to the hybrid architecture, it is possible to gradually implementation of SDN solutions in existing networks, while these solutions will be tightly integrated and interact with equipment that does not support SDN and the OpenFlow protocol. This, in particular, allows you to use the benefits that provide SDN-applications, without the need for a complete replacement of all equipment in the network.
Keywords: Data center network, software defined networking, SDN, OpenFlow, out-of-band, in-band, TCP-window, POX, moment characterstics.

DEVELOPMENT AND RESEARCH OF THE SOFTWARE AND HARDWARE COMPLEX FOR RECEPTION AND TRANSMISSION OF INFORMATION IN MOLECULAR NANO-NETS
E. Kuznetsova, V. Kulik, M. Zakharov, R. Kirichek
Abstract: In the past decade, in connection with the popularization of the concept of the Internet of Things and the ubiquitous increase in the number of devices connected to a wireless network, there is the task of organizing networks in which information can be transferred in other ways, for example, by moving the substance microparticles. Research subject. The article is devoted to the development of the architecture of a software and hardware complex for measuring and collecting various indicators of the air environment through the Internet of Things technology and examines the problems arising from its application in molecular networks. Method. The architecture of the developed model network is considered. Experiments have been carried out that made it possible to compare under what conditions information is best received, and which substance is suitable for transmitting information. Core results. Has been developed a software and hardware complex for receiving and transmitting information in molecular nanonetworks. An experiment was conducted on the possibility of receiving information and transforming it into a digital form, using the developed model network. Practical relevance. The developed model network can be used for traffic analysis.
Keywords: Internet of Things, IoT, molecular nano-nets, volatile organic compounds.

ANALYSIS OF THE TECHNICAL AND ECONOMIC CONSEQUENCES OF THE IMPLEMENTATION OF THE TELECOMMUNICATION NETWORKS WITH ULTRA-LOW LATENCY
N. Chistova, A. Koucheryavy
Abstract: The development of the public telecommunications networks in the past few years is generally characterized by the upcoming large-scale implementation of the concept of the Internet of Things. However, another new technology may be have a much more significant impact on telecommunication networks and on society as a whole, primarily on the implementation of the digital economy. We are talking about telecommunication networks with ultra-small latency, a comprehensive analysis of the technical and economic consequences of the implementation of which is analyzed in the paper. The implementation of such networks will lead to the decentralization of the network and the decentralization of the economy. The paper provides an example of the needs of networks in data centers, the number of which in the implementation of networks with ultra-low latency will be in the thousands. Research subject. Fifth generation telecommunication network. Method. System analysis. Core results. The task of the implementation telecommunication networks with ultra-low latency is interdisciplinary, which already requires a complex of research and development work in this direction. Practical relevance. Determined the needs of networks in data centers.
Keywords: telecommunication networks with ultra-low latency, network clustering, digital economy.

USING THE PRINCIPLE OF CONNECTIVITY IN THE DIGITAL OBJECTS ARCHITECTURE FOR THE TRACEABILITY AND COMBATING COUNTERFEIT
A. Yankovsky, M. S. N. Al Bahri, R. Kirichek, A. Borodin
Abstract: The extensive distribution of modern electronics and communications technologies simplifies the process for users to obtain a huge number of various services, ranging from telecommunications to the usual for everyone shopping in the store or on the Internet. With all this, the originality of products is still under the threat of counterfeit. There are many solutions to protect goods from counterfeiting, the use of which in consumer goods would lead to additional costs of production, and, consequently, to higher prices for products, and faking the protection system is only a matter of time. Research subject. The article is devoted to the identification of Internet of things devices and applications, as well as methods to combat counterfeit. Method. Methods of applying the digital objects architecture for the identification of goods and services, for traceability and anti-counterfeiting are considered. Core results. The article presents the results of adapting the digital objects architecture for the traceability of goods and the fight against counterfeit by incorporating delegation methods into the existing architecture. For these purposes, metadata of Handle type records with their storage in the LHS and GHR bases are used, which allow to ensure the coherence of objects. Practical relevance. A key feature of the concept is integration with the existing international Handle System, which allows you to organize the interaction of related systems at the state level in various sectors of the economy, such as trade, industry, agriculture and others.
Keywords: Internet of Thing, digital object, architecture, identification, connectivity, counterfeit, register, traceability.
