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.
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.
The article considers the approach to constructing a multi-level architecture of a distributed system of energy monitoring based on Internet of Things (IoT) technology. The technology is implemented on a basis of controllers, remote access to which is carried out via the Internet. Such a network has a large number of nodes. The routing of information packets in such a network is possible through the IPv4 and IPv6 network protocols, over which MQTT data transfer is organized. This simple network protocol implements the exchange of messages between the active nodes of the telecommunications network of the energy monitoring system based on the publication-subscription principle. This telemetry architecture template provides the ability for smart sensors, accounting nodes, controllers and data collection devices, which support the MQTT protocol, communicate and publish messages that were not previously known or predefined. Research has been completed under the PNRPU grant No.2016/PI-2 «Methodology development of monitoring and heat flow utilization as low potential company energy sources»
This book is the very first book-length study devoted to the advances in technological development and systems research in cooperative economics. The chapters provide, first of all, a coherent framework for understanding and applying the concepts and approaches of complexity and systems science for the advanced study of cooperative networks and particular cooperative enterprises and communities. Second, the book serves as a unique source of reliable information on the frontier information technologies available for the production, consumer, credit, and agricultural cooperative enterprises, discussing predominant strategies, potential drivers of change, and responses to complex problems. Given the diverse range of backgrounds and advanced research results, researchers, decision-makers, and stakeholders from all fields of cooperative economics in any country of the world will undoubtedly benefit from this book.
