Rapid progress in the field of industrialization and informatization methods has led to huge progress in the development of nextgeneration production technologies. The Internet of Things (IoT) is a pervasive technology, and now it is used in all areas of everyday life, from healthcare to technological production. The new industrial revolution began with connected technologies supported by the Internet of Things. However, the security of the Internet of Things is still an open question since in case of unauthorized access, data from sensors can be changed, for example, by a user with authorized access rights, which can lead to unforeseen consequences.

The emergence of Industry 4.0 has led to the development of high-tech solutions that influence a number of related activities. In the field of warehousing management, as an important element of logistics systems, there is also an impact that follows a certain model. Warehousing 4.0 and related developments have to be supported by a number of basic technologies for automatic identification, and technologies that represent intelligent connections to the real world. One of these is the Internet of Things (IoT), which is essentially based on many other solutions, including radiofrequency identification (RFID). The report presents some aspects of the application of RFID in the management of warehousing processes, and also reveals some basic practices of trade and manufacturing enterprises in that field. The study represents the results of a survey focused on warehousing management practices in Bulgaria. The results reveal some fundamental aspects of radiofrequency identification practices as a prerequisite for smart warehousing. The general findings are related to the relatively low and insufficient level of RFID technology usage in the field of warehousing.

This paper discusses a case of implementing Industry 4.0 solutions with existing legacy informational system in cement-producing factory. One of the main reasons the company wants to keep its existing ERP solution is because is too complex and cannot be ported to a contemporary computer architecture. The plant also needs to automate and modernize the process of loading their products, but the company management does not want to invest in modern computer servers and a new ERP system. That’s why they decided to implement a hybrid solution – a modern Industry 4.0 IoT devices with .NET client application using the existing legacy DEC Alpha as a server. Here, the required technologies used for developing that software solution are overviewed and all parts of the software solution are described. Finally, the benefits and effectiveness of such a hybrid software solution are shown.

Future of modern communication technologies of smart modern production systems is moving to wireless form of data transfer between devices. Thanks to use of smart devices that communicate within the network, we are talking about of interconnection of separate devices – Internet of Things (IoT). In connection with the implementation of standards Industry 4.0 in the manufacturing process together with IoT implementation into production process a new term is created – Industrial Internet of Things (IIoT). However, the implementation of this form of wireless communication brings some problems, mainly in field of safety and stability of data transfers. This paper provides a brief overview of the current state of the use of IIOT in industrial communication and production management and describes relationships to concepts such as cyber-physical systems and Industry 4.0. Part of the article is a proposal of communication scheme suitable for the implementation on model of modular production system (MPS).

The Smart Homes come rapidly into our everyday lives bringing comfort, security, help and many other benefits. The development of Information and Communication Technology and the advances in the applications based on Internet of Things emerged the appearing of more and more Smart Home solutions. The Smart Home System should implement default or custom integrated functions and intelligent self-adaptive methodology, based on the analysis of the habits, requirements and preferences of its inhabitants.
In this paper the authors consider the development of Android and Wi-Fi based remote control Smart Home System, which integrates the analysis of the survey of the everyday habits of the people. An analysis of habits of 64 surveyed people was made. The results can be taken into account during the process of defining the default integrated functions at the stage of designing a Smart Home. The presence, absence or approaching certain location by the people are included as elements of the Smart Home System.

Technology and innovations have powered the evolution of Industry4.0, the fourth industrial revolution.
State-of-the-art technologies such as the Internet of Things (IoT), cloud computing (CC), big data analytics (BDA), and artificial intelligence (AI) – all part of Industry4.0, have greatly stimulated the building industry. Digital Тwin is a significant enabler for Industry 4.0 initiatives. Within Industry 4.0, the amount of digital product information generated and collected over the entire lifecycle has been growing.
Although digital twins have been around for several decades, the rapid rise of the internet of things (IoT) is that they have become more widely considered as a tool of the future. Digital twins are getting attention because they also integrate things like artificial intelligence (AI) and machine learning (ML) to bring data, algorithms, and context together
A ―digital twin‖—or digital replica of a physical entity—can target building industry in several sub-areas:
– Facility management
– Product Lifecycle Management
– Smart Buildings
– Smart energy
All these areas are one giant step further by creating a Digital Twin — a virtual representation of real-world buildings that can be viewed and scrutinized in minute detail. This research describes business cases and best practices in design of IoT Solutions for building industry, powered by Digital Twins. A reference architecture and prototypes which demonstrate application of Digital Twins in Smart are created as a result of this study .This research is technology agnostic, but prototypes of sample solutions are considered in the context of Microsoft Azure (Azure solutions, covering Azure Digital Twins Service and Azure IoT Stack.)

In order to make better decisions in the precision agriculture the measurement of air pollution parameters such as PM10, NOx, SO2, CO, O3 and agriculture parameters such as air temperature, humidity, soil moisture and leaf wetness are of crucial importance. Making analysis using different AI technics based on these parameters can bring better yield and quality in the food production process. In this paper, we present our approach in building an environmental air quality monitoring system as a support for precision agriculture by using Arduino [5] open-source electronics platform.

BlockChain is a distributed database of records or public ledger of all time stamped transactions saved in all computers in one peer-to-peer network. It allows a secure and transparent transfer of digital goods including money and intellectual property. Bitcoin – a digital decentralized cryptocurrency, is the first application of BlockChain. The second application is an agreement called Smart contract that enables exchanging a value or assets between two owners based on a set of conditions included in the contract.

In this paper, we analyze the possibilities for application of BlockChain in Big Data and IoT. Implementation of BlockChain in Big Data confirms that data is accurate and secure and sharing of data will become more simple. In industries like financial services, government and healthcare there is a need to combine BlockChain and Big Data because these industries have repositories full of important data. They must store and share these large amounts of data. Implementation of BlockChain technology provides security of data and ensures its integrity when shared. BlockChain technology is also seen as a way to secure the Internet of Things (IoT). Application of BlockChain in IoT enables IoT devices to participate in BlockChain transactions and invents new styles of digital interactions. This technology will provide a simple infrastructure for devices to directly and securely transfer data or money using Smart contract.

The Fourth Industrial Revolution implies a total change in our way of life. To be adequate to the new security threats stemming from high technology, we need to analyze and evaluate them from the point of view of people’s security.

5-th generation mobile networks aim higher capacity than current 4G, allowing higher number of mobile broadband users per area unit, and allowing consumption of higher or unlimited data quantities in gigabyte per month and user. 5G research and development is extremely important for the security of the human society. 5 G will have applications not only in the army and the police, but in the public transport, video monitoring, Internet of Things (IoT) etc. aiming at lower cost, lower battery consumption and lower latency at GHz frequency bands (millimeter waves). The use of directional antennas and space diversity at these extremely high frequency bands will improve the secure work of such systems. SCP-RPSC (Spatial Correlation Processing – Random Phase Spread Coding) is an entirely new approach in the field of microwave antenna theory, developed by the author one decade before. Its applications in the future terrestrial, High Altitude Platform Systems and satellite 5 G communications is considered in the report. Block schemes and advantages of the proposals are given too.
