Smart City is a city environment that advanced sensors combine to manage the city's assets the information technology virtually. Data they have collected, because it is the foundation of these services, the sensor network is an integral part of the smart city. Wireless sensors are to be deployed in several different locations, therefore a relatively inexpensive ability to transmit remote data to reduce the power consumption and maintenance costs; the small built-in sensor is incredibly essential. For each sensor, since it prerequisites for complex information, and Smart City needs is rugged, the integrated sensor system is the concept of Smart City in development. The most important thing is the smart city's side, and the reverse in urban design the plan is to reveal the importance of the role of landscape design. The purpose of this article is, from the point of view of urban design, find outlines the concept of Smart City, highlighting important touchpoint of smart urban landscape design that leads to strong principles of smart, relations and the role of urban design, planning and creativity it is to be sustainable development, city to allow for efficient urban development and beautiful urban landscape. 相似文献

Presently, a very large number of public and private data sets are available from local governments. In most cases, they are not semantically interoperable and a huge human effort would be needed to create integrated ontologies and knowledge base for smart city. Smart City ontology is not yet standardized, and a lot of research work is needed to identify models that can easily support the data reconciliation, the management of the complexity, to allow the data reasoning. In this paper, a system for data ingestion and reconciliation of smart cities related aspects as road graph, services available on the roads, traffic sensors etc., is proposed. The system allows managing a big data volume of data coming from a variety of sources considering both static and dynamic data. These data are mapped to a smart-city ontology, called KM4City (Knowledge Model for City), and stored into an RDF-Store where they are available for applications via SPARQL queries to provide new services to the users via specific applications of public administration and enterprises. The paper presents the process adopted to produce the ontology and the big data architecture for the knowledge base feeding on the basis of open and private data, and the mechanisms adopted for the data verification, reconciliation and validation. Some examples about the possible usage of the coherent big data knowledge base produced are also offered and are accessible from the RDF-store and related services. The article also presented the work performed about reconciliation algorithms and their comparative assessment and selection. 相似文献

The new Internet of Things (IoT) applications are enabling Smart City initiatives worldwide. It provides the ability to remotely monitor, manage and control devices, and to create new insights and actionable information from massive streams of real-time data. The main features of a smart city include a high degree of information technology integration and a comprehensive application of information resources. The essential components of urban development for a smart city should include smart technology, smart industry, smart services, smart management and smart life. The Internet of Things is about installing sensors (RFID, IR, GPS, laser scanners, etc.) for everything, and connecting them to the internet through specific protocols for information exchange and communications, in order to achieve intelligent recognition, location, tracking, monitoring and management. With the technical support from IoT, smart city need to have three features of being instrumented, interconnected and intelligent. Only then a Smart City can be formed by integrating all these intelligent features at its advanced stage of IOT development. The explosive growth of Smart City and Internet of Things applications creates many scientific and engineering challenges that call for ingenious research efforts from both academia and industry, especially for the development of efficient, scalable, and reliable Smart City based on IoT. New protocols, architectures, and services are in dire needs to respond for these challenges. The goal of the special issue is to bring together scholars, professors, researchers, engineers and administrators resorting to the state-of-the-art technologies and ideas to significantly improve the field of Smart City based on IoT. 相似文献

Innovating and Exploiting Entrepreneurial Opportunities in Smart Cities: Evidence from Germany 下载免费PDF全文
Sascha Kraus Chris Richter Savvas Papagiannidis Susanne Durst 《Creativity & Innovation Management》2015,24(4):601-616
Smart City initiatives are considered a vehicle for achieving sustainable development of urban growth. This paper explores the conditions and factors that affect innovation in Smart Cities from an entrepreneurial vantage point. Data was obtained through a series of interviews with German entrepreneurs active in Smart Cities. Beyond examining the importance of a set of factors that originate from the extant literature, our findings suggest that entrepreneurs believe that Smart City initiatives need a clear vision to drive their development and growth and that government has a key role to play in bringing the necessary resources and stakeholders together. 相似文献
