The creation of projects in the Proteus program based on microcontrollers is considered. A classic 8051 microcontroller from Intel is investigated, as well as an STM32F401RE microcontroller from ARM. The development of the simplest programs for use in laboratory classes on programming embedded systems (for example, the "Internet of things") for 8051 – in assembler language, for STM32F401RE – in C language using a special development environment is carried out. The research can be used in laboratory classes on embedded systems programming.

The content of the cyberphysical approach to the creation, functioning and improvement of transport and production systems is analyzed. It was found out how, on the basis of the approach, cyberphysical transport and production systems are created as the integration of special technologies of the Internet of Things; embedded systems; ubiquitous and cloud computing. It was revealed that cyberphysical transport and production systems have a trinitarian concept and are defined by three entities: communication, computation and control, which unites information. It is determined that the main functions of cyberphysical transport and production systems are: information processing, intelligent communications, performance and process control. A component model of such a system has been built, which includes two groups of components - evolutionary and technological. The evolutionary group of components includes subsystems: digital; integrated; robotic, intelligent distributed. These components are a kind of basis for the presence of prerequisites for the creation of transport and production systems. It is noted that the technology group of components is the basis for concrete implementations of the Internet of Things, embedded systems and ubiquitous and cloud computing. A cyberphysical system of technical service is proposed as a specific implementation of cyberphysical transport and production systems. It was determined that the modes of the proposed functional cyber system are: high adaptability; an appropriate level of efficiency; intelligence of management; high level of reliability; the use of a new on-net online simulation type; using a new type of self-verifying models; internal online optimization, etc. It is shown that the presence of intelligent models in the cyberphysical model of technical service makes the system resistant to cyberattacks and increases the degree of safety when ensuring traffic in transport and the development of an occupational safety system during maintenance and repair operations.

PurposeThe purpose of this study is to investigate how the internet of things (IoT) contributes to manufacturers' advanced services development and delivery. To better understand the creation of these IoT contributions, the study adopts a socio-technical research perspective, which expands the scope of the investigation and integrates the technological, information and social factors that enable these IoT contributions.Design/methodology/approachA multiple-case research method was employed to investigate the IoT contribution scenarios of 15 manufacturers who offer advanced services and to examine their dependence on other non-IoT factors, using thematic analysis.FindingsThe analysis identified five advanced services value propositions, which are enabled by nine “IoT-enabled information systems (IS) artefacts” that specify the distinct interactions between the technological, information and social subsystems supporting the manufacturers' advanced services value propositions.Originality/valueThe study advances the servitisation research by demonstrating that IoT technology on its own is insufficient for the creation of the IoT contributions. It shows, instead, the need for close interactions with a diverse range of other factors, which are often not considered when developing an IoT strategy. The study also introduces the IS artefact notion as a unit of analysis that constitutes an alternative to the commonly adopted techno-centric perspective used to conceptualise IoT contributions. The study and its findings add to the development of a socio-technical perspective on the IoT in advanced services and thereby suggests a number of theoretical and practical implications.

This study presents the results of an experimental research with the use of 3D resources, such as the creation and printing of physical objects, that can serve as interface for 3D devices, The creation of solutions for the internet of things, requires, besides the knowledge of programming, electronics, internet and computing, also requires the creation of parts, which are often complex, for coupling and manipulation of devices to the internet of things. Personal experience during computer classes was the main motivation for the development of this work, demonstrating how to create solutions that can meet the different projects that involve the internet of things. In addition to presenting the results of a comparison between some tools evaluated during the research. The results were collected during the creation of the objects in 3D systems, besides presenting the results in pieces that were printed with this technology, these results demonstrated the possibility of creating viable solutions and that can serve as a model for new projects, facilitating the development of solutions to the internet of things.

JavaScript language (JS) has been widely used in recent years applied to browsers-context. Yet JS is being applied to other backgrounds such as server-side programming, mobile applications, games, robotics, and the Internet of Things (IoT). JavaScript is suitable for programming IoT devices due to eventdriven oriented architecture. However, it is an interpreted language, so it has a lower performance than a compiled language. This paper assesses the use of WebAssembly as a strategy to improve the performance of JavaScript applications in the IoT environment. The experiments were performed on a Raspberry Pi using the Ostrich Benchmark Suite. We run the algorithms in JavaScript, WebAssembly, and C language while collecting data about device resource consumption. Our results showed that JavaScript performance could be improved by 39.81% in terms of execution time, a tiny gain in memory usage, and reduced battery consumption by 39.86% when using WebAssembly.

The Internet of Things is a network of physical devices consisting of embedded systems and sensors that interact with each other and connect to the Internet, and the quick growth of the Internet of Things industry has resulted in complex inter-networking on the Internet. Software-defined networking is a recent advance in computer networking that redefines the network paradigm for future communication, and the advantages of software-defined networking can also be applied to Internet of Things, namely as software-defined Internet of Things. In this article, we investigate the vulnerability of the software-defined Internet of Things platform device manager, which monitors the connected Internet of Things devices in the network. Although being the one that performs one of the most crucial services, the device managers in current primary controllers have a big security issue as they do not include any device verification, authentication, or authorization routines. Consequently, the device manager accepts all the changes of device information made by other devices, which leads to potential attacks as demonstrated in this article. To address this problem, a comprehensive and lightweight countermeasure is proposed and its effectiveness is verified through experiments.
