Baranov (Internet of Things: Future Telecommunication) introduces the possible changes in social patterns of the provisionoftelecommunicationservicesunderinfluenceofusingInternetofthings (IoT)technology.Inparticular,somesocialmodelsoftelecommunicationoperators v vi Preface and models of the requirements of subjects to receive telecommunication services are presented. The impact of the use of IoT technologies on the activities of telecommunication operators is analyzed. The directions of the possible transfor- mation of the business model of a telecommunication operator that will help meet the needs of users of IoT technology are considered. The features of the constructionofthetelecommunicationinfrastructureoftheoperatorintheinterests of meeting user needs are considered. It is shown that the use of IoT technologies significantly increases the load on the radio frequency resource. The technical features and legal models of increasing the efficiency of using radio frequency resource in Ukraine are presented. Chapter Cryptographic Technology Blockchain and its Applications by A. Luntovskyy and D. Guetter focuses on the problem of using blockchain technologies and their networked cryptographic applications. An important trend since approximately the year 2000 is the use of modern cryptotechnology “blockchain” for acceleration, transparency, and decentralization of financial transactions and as promising digital payment instruments and cryptocurrencies (e.g., Bitcoin, Monero, and Ethereum). The influencing factors and sources of blockchain cryptotechnology were dis- cussed, the comparison of centralized bank systems vs. decentralized systems was carriedout,theminingprocessforcryptographiccurrencies,theconceptofapublic ledger, the validation principles PoW and PoS are represented, as well as the profitability of cryptographic currencies was analyzed. Furthermore, important applications of blockchain cryptotechnology were shown (such as Smart Contracting,Bletchley)aswellastheaccompanyingrisks,andtheiradvantagesand disadvantages are discussed. In addition, the malicious applications are discussed such as the ransomware (extortion Trojans). Finally, the potential and future perspectives of blockchain cryptotechnology for real business applications are assessed. Chapter Model of transdisciplinary representation of GEOspatial information by O. Stryzhak, V. Prychodniuk, and V. Podlipaiev covers intellectual systems for knowledge extraction and their applications for GIS. On the basis of analysis of the text primary structure, which is formed during its lexical analysis, the pos- sibilityisdeterminedandthemethodofstructuring naturallanguagetextswiththe helpoftherecursivetextreductionprocedureusingtherulespresentedintheform of lambda expressions is proposed. It is shown the possibility of dynamically forming such rules by users without special training on the basis of the original structure of the texts is already analyzed. An ontological model of an interactive documentisproposed,whichisintendedtoanalyzetheresultsoftextstructuringby theexpert.ThemodelofontologicalGISapplicationisaninteractivedocumentthat allows using affine space to display geospatial information upon request. The models of the interactive document and the ontological GIS application provide a high representative level of information available in text documents (in particular, geospatial). The method described in the chapter allows us to form a structured representation of texts to provide the possibility the information processing Preface vii contained in the text by automatically or used computer-aided tools. The model of transdisciplinary information representation implementation as an interactive doc- ument function allows quick access to large arrays of thematic information, and in combination with ontological GIS application it solves the problem of transdisci- plinary representation of geospatial information. Chapter Quality Control for Mobile Communication Management Services in Hybrid Environment by L. Globa, M. Skulysh, O. Romanov, and M.Nesterenkoinvestigatedthefeaturesofthequalitycontrolservicethatservicing of flows in the mobile communication network.

Today,thereisagrowingneedforwell-scalablecommunicationsystemsthatmeet the needs of end-users due to dynamically changing service structure provided to end-users and constantly changing requirements for service quality indicators with thegrowthoftrafficvolumes.Ofparticularimportancearethemanagementsystems of service. In this chapter, the features of quality control service, which controls flowsofthemobilecommunicationnetwork,areinvestigatedwiththeuseofpartial virtualization of network functions. An architectural solution is proposed for organizing service streams in a hybrid environment. It includes a telecommunica- tion network and cloud computing resources that provide servicing of virtualized functions involved in the organization of service streams. The solution for improving the PCRF system and some procedures that allow ensuring quality controlofserviceflowsandcontrollingthecomputingresourcesofahybridsystem, whose work affects the quality of servicing of service flows of the system, is proposed. In Improved Estimates for the Reliability Indicators of Information and Communication Network Objects with Limited Source Information, D. Mogylevych and I. Kononova present analytical relationships for quantitative assessment of the lower and upper bounds of reliability indicators for telecom- munication objects of two classes: a) objects with structural redundancy, in which the connection time of backup elements is so small that it can be almost neglected andb)objectswithstructuralandtemporaryredundancy,inwhichconnectiontime isthefinal(usuallyrandom) quantity.Theanalysisoftheserelations allowedusto distinguish functionals characterizing the reliability of the objects under consider- ation, for which exact boundary values were determined. These results made it possible to obtain two-sided assessments of the reliability indicators of the objects of the above classes under conditions when information on the distribution func- tionsoftheconnectiontimeofbackupelementsandtherecoverytimeislimitedby knowledge of only two initial moments. An important case for practice is also considered, when along with permanent refusals in the equipment of an object, failuresmayalsooccur.Analyticalrelationshipshavebeenobtainedthatallowusto viii Preface calculate two-sided assessments of the reliability indicators of objects with struc- tural and temporary redundancy, when equipment failures are taken into account alongwithrefusals.Thischapterconcludeswithastatementoftheresultsthatallow ustofindtwo-sidedassessmentsofthereliabilityindicatorsofsystemswithaserial (in the sense of reliability) connection of objects when structural and temporary redundancy is provided. Part II Telecommunication Technologies and Research. M. Ilchenko, S. Kravchuk, and M. Kaydenko (Combined Over-the-Horizon Communication Systems) present the scientific and technical principles of con- struction of new hybrid combined over-the-horizon communication systems with the use of reference small-sized stations of tropospheric communication, relaying intellectual aeroplatforms, and artificial formations. These principles are based on the use of new technologies and software-defined and cognitive radio, cooperative relaying, machine-to-machine, effective interaction system, hardware, and appli- cation protocol levels. In Prospects for the Development of Geostationary Satellite Communications Systems in the World, T. Narytnyk and S. Kapshtyk are concerned with some issues related to the current state and prospects of development of satellite com- munication systems GEO in the context of the market of satellite communication services and using in the space segment technical solutions.
