Разработка универсального устройства «Aquauino» для автоматизации жизнеобеспечения аквариума
Variety of systems were developed based on the Internet of Things (IoT) concept including autonomous systems, which operate without human intervention. Development of such systems requires not only data from devices, but also interaction between these devices. It is necessary that one IoT-system could control other devices behavior. There are several problems related to that task including problem of incompatibility of different IoT APIs, requiring software support of each device in the system. This problem considerably restricts joint use of different devices from different IoT-systems. In this paper there is a method of control over the IoT-system is proposed. This method solves the problem described above. The method includes development of IoT API based on ontologies using Linked Open Data. The IoT interaction in the described method involves using control requests in the form of ontologies. The new ontologies synchronization mechanism is described which implemented links in Linked Open Data datasets allowing the dictionaries unification.
The paper presents the results of the review and analysis of media content management systems on the basis of the mirrors. We present descriptive model and architecture of the developed system. The novelty consists in the development of a new device that allows users to interact with the Internet and manage media content using augmented reality. The article considers designed logical and physical model of system hardware and describes developed algorithms of the system. There are described a soft shell and new algorithms that significantly increase the amount of user interaction with his reflection, internet and media content using augmented reality.
The paper describes the possibility of using the Internet of Things in retail industry as well as potential of using internet of things in Russia. The research objective is to identify the possibilities of using Internet of Things in retail process such as supply, logistics, client service and marketing and to give the examples for getting economy and cost reduction in industry. The author provides recommendations of using internet of things technology in retail, taking into considerations existing aspects and current worldwide trends of global transformation, digitalization and cloud technologies.
A heterogeneous wireless network consists of various devices that generate different types of traffic with heterogeneous requirements for bandwidth, maximal delay and energy consumption. An example of such networks is a Wi-Fi HaLow network that serves a big number of Machine Type Communication battery-powered devices and several offloading client stations. The first type of devices requires an energy-efficient data transmission protocol, while the second one demands high throughput. In this paper, we consider a mechanism that allocates a special time interval (Protected Interval) inside of which only battery powered-powered devices can transmit. We show that appropriate selection of the Protected Interval duration allows battery-powered devices to consume almost the minimal possible amount of energy on the one hand, and to provide almost the maximal throughput for offloading stations on the other hand. To find such duration, we develop a mathematical model of data transmission in a heterogeneous Wi-Fi network.
In the last decade, the Internet of Things (IoT) has affected the approach of organizations to innovation and how they create and capture value in everyday business activities. This is compounded in the so-called Smart Cities, where the objective of the IoT is to exploit information and communication technologies (ICTs) to support added-value services for citizens, giving companies more opportunities to innovate through the use of the latest technologies. In this context, multinational enterprises (MNEs) are building alliances, starting several projects with public and private city stakeholders aimed at exploring new technologies for cities but also at exploiting new IoT-based devices and services in order to profit from them. This implies that companies need to manage and integrate different types of knowledge to efficiently and effectively support the simultaneous pressure of exploration and exploitation, at a project portfolio level. Using structural equations modeling with data collected from 43 IoT smart city project alliances in Italy, this paper tests and finds evidence that MNEs need to develop knowledge management (KM) capabilities combined with ICT capabilities if they want to obtain greater ambidexterity performance at the project portfolio level. More specifically, we highlight that KM capabilities enhance alliance ambidexterity indirectly through firms' ICT capabilities, suggesting that MNE managers should design KM tools and develop new ICT skills. Implications for academics, managers and future lines of research are proposed.
