A survey on IEEE 802.11ah: An enabling networking technology for smart cities
Smart technologies play a key role in sustainable economic growth. They transform houses, offices, factories, and even cities into autonomic, self-controlled systems acting often without human intervention and thus sparing people routine connected with information collecting and processing. The paper gives an overview of a novel Wi-Fi technology, currently under development, which aims to organize communication between various devices used in such applications as smart grids, smart meters, smart houses, smart healthcare systems, smart industry, etc.
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 6th International Conference on Theory and Practice of Electronic Governance, ICEGOV2012, was organized in Albany, New York, United States (US) from the 22nd to the 25th of October 2012, hosted by the Center for Technology in Government, University at Albany, State University of New York under the patronage of the United States National Archives and Record Administration. The ICEGOV (International Conference on Theory and Practice of Electronic Governance) series focuses on the use of technology to transform relationships between government and citizens, businesses, civil society and other arms of government (Electronic Governance).
This book constitutes the refereed proceedings of the First International Workshop on Wireless Access Flexibility, WiFlex 2013, held in Kaliningrad, Russia, in September 2013. The 13 full papers presented were carefully reviewed and selected for inclusion in this volume. The papers describe the latest results and novel research ideas in the field of flexible wireless access architecture design opening the door for innovative solutions significantly improving network performance. The following topics are covered in this volume: 4G and beyond, local area networks, multi-hop networks, sensor networks.
Ancient Rome and Athens were once considered by every indication, great cities! European cities have endured a number of long wars that nearly destroyed them permanently. In the U.S., the City of San Francisco was nearly wiped out by the earthquake of 1906 and in 1871 the City of Chicago was nearly destroyed by fire. In nearly every case, these major cities were able to recover, rebuild, transform, making them stronger and more resilient. Today the so-called “smart cities” movement is based in part on the confluence of new technologies, economic growth, a re-evaluation of quality of life factors, as well as the resurgence of interest in cities across the globe. For example, only recently have we witnessed the trend towards urban growth in American cities. Today the outward migration has reversed itself after decades of residents moving to the suburbs or further out to rural parts of the country. Now, people are returning to our cities, or have decided not to leave as their forefathers had before them. This reinforces the need to re-think and to act differently when it comes to urban planning and maintaining sustainable cities. Even the smartest of cities can not rest on their past success. Smart cities require a constant process of vision, execution, and renewal, which makes it more a journey than a destination. There are many elements that comprise a smart or intelligent city. This book was created to further explore those elements and the pathways towards becoming and maintaining a smart city. This book is a collection of works from thought-leaders across the globe, with authors currently residing in no less than 10 countries including France, Spain, Italy, Belgium, South Africa, Japan, Saudi Arabia, Singapore, and Russia, in addition to the United States. The twenty-seven chapters reveal that there is far more in common than not, as each author shares their research and insights, all aimed at helping the reader better understand and appreciate the contemporary smart city movement. As the smart cities movement gains attention, some have been critical - going as far to say that this is only a passing fad or a relabeling of current events. Whether this is a fad or not, one thing is crystal clear, cities are growing and are here to stay. It is an undeniable fact that growing populations place an enormous strain on our cities in terms of transportation, infrastructure, public safety, health, education, and the quality of natural resources such as water and air. Finally there is the issue of energy and sustainability from an environmental perspective. The fall of ancient Rome may not have happened in a day, but its decline and those of other, once great, cities provide both lessons and warnings that are instructive. These lessons remind us that in the end cities are a profound collection of citizens, and without their meaningful engagement we may be left with cities that are no longer smart.
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»
