Several cities have recently moved towards becoming smart cities for better services and quality of life for residents and visitors, with: optimized resource utilization; increased environmental protection; enhanced infrastructure operations and maintenance; and strong safety and security measures. Smart cities depend on deploying current and new technologies and different optimization methods to enhance services and performance in their different sectors. Some of the technologies assisting smart city applications are the Internet of Things (IoT), fog computing, and cloud computing. Integrating these three to serve one system (we will refer to it as integrated IoT-fog-cloud system (iIFC)) creates an advanced platform to develop and operate various types of smart city applications. This platform will allow applications to use the best features from the IoT devices, fog nodes, and cloud services to deliver best capabilities and performance. Utilizing this powerful platform will provide many opportunities for enhancing and optimizing applications in energy, transportation, healthcare, and other areas. In this paper we survey various applications of iIFCs for smart cities. We identify different common issues associated with utilizing iIFCs for smart city applications. These issues arise due to the characteristics of iIFCs on the one side and the requirements of different smart city applications on the other. In addition, we outline the main requirements to effectively utilize iIFCs for smart city applications. These requirements are related to optimization, networking, and security.

Allocation Method

Nowadays, cities are intended to change to a smart city. According to recent studies, the use of data from contributors and physical objects in many cities play a key element in the transformation towards a smart city. The ‘smart city’ standard is characterized by omnipresent computing resources for the observing and critical control of such city’s framework, healthcare management, environment, transportation, and utilities. Mist computing is considered a computing prototype that performs IoT applications at the edge of the network. To maintain the Quality of Service (QoS), it is impressive to employ context-aware computing as well as fog computing simultaneously. In this article, the author implements an optimization strategy applying a dynamic resource allocation method based upon genetic algorithm and reinforcement learning in combination with a load balancing procedure. The proposed model comprises four layers i.e. IoT layer, Mist layer, Fog layer, and Cloud layer. Authors have proposed a load balancing technique called M2F balancer which regulates the traffic in the network incessantly, accumulates the information about each server load, transfer the incoming query, and disseminate them among accessible servers equally using dynamic resources allocation method. To validate the efficacy of the proposed algorithm makespan, resource utilization, and the degree of imbalance (DOI) are considered as the scheduling parameter. The proposed method is being compared with the Least count, Round Robin, and Weighted Round Robin. In the end, the results demonstrate that the solutions enhance QoS in the mist assisted cloud environment concerning maximization resource utilization and minimizing the makespan. Therefore, M2FBalancer is an effective method to utilize the resources efficiently by ensuring uninterrupted service. Consequently, it improves performance even at peak times.

A fejlesztéspolitikában ma a „smart” címkével minden vonzóbb, eladhatóbb, a kifejezés sokszor a ’környezetbarát’ vagy ’fenntartható’ szinonimájaként is használatos. A városfejlesztésben az utóbbi idők egyik legfelkapottabb paradigmája, globális szintű versengést indítva mind a városok, mind az érdekelt vállalatok között a kölcsönösen hasznosnak vélt előnyök reményében. A szerzők egyrészt annak jártak utána, miért éppen most virágzott fel a smart city mint fejlesztési paradigma, és milyen tényezők indukálták gyors előretörését. Másrészt a nemzetközi példák bemutatásán keresztül arra a kérdésre keresik a választ, milyen társadalmi hatásokkal járnak ezek a fejlesztések, milyen kihívásokkal kell szembenézni a smart city fejlesztések kapcsán, és vajon a jövőben a fejlesztési szereplők képesek lesznek-e tanulni hibáikból, és tudatosan tervezni a hatások összességével. --- Do smart cities intensify social exclusion? In development policy everything seems to be more attractive and marketable when labelled ‘smart’; the expression is often used even as a synonym for ‘environmentally-friendly’ or ‘sustainable’. Considering urban development projects, smart city development is one of the most popular paradigms, triggering global competition between cities as well as the interested companies, both expecting mutual benefits from the co-operation. The article, on the one hand, tries to reveal, why the smart city paradigm has now started to thrive, and what factors played a part in its rapid development. On the other hand, through the presentation of international practices, the authors intend to answer what social impacts these developments have had, what challenges have the smart city developments met, and whether in the future the actors could learn from their mistakes and consciously take into account the complexity of impacts.

Purpose – Contemporary debate is increasingly focused on ICT and sustainability, especially in relation to the modern configuration of urban and metropolitan areas in the so-called smartization process. The purpose of this paper is to observe the connections between smart city features as conceptualized in the framework proposed by Giffinger et al. (2007) and new technologies as tools, and sustainability as the goal. Design/methodology/approach – The connections are identified through a content analysis performed using NVivo on official reports issued by organizations, known as industry players within smart city projects, listed in the Navigant Research Report 2013. Findings – The results frame ICT and sustainability as “across-the-board elements” because they connect with all of the services provided to communities in a smart city and play a key role in smart city planning. Specifically, sustainability and ICT can be seen as tools to enable the smartization process. Research limitations/implications – An all-in-one perspective emerges by embedding sustainability and ICT in smart interventions; further research could be conduct through direct interviews to city managers and industry players in order to understand their attitude towards the development of smart city projects. Practical implications – Potential approaches emerging from this research are useful to city managers or large corporations partnering with local agencies in order to increase the opportunities for the long-term success of smart projects. Originality/value – The results of this paper delineate a new research path looking at the development of new models that integrate drivers, ICT, and sustainability in an all-in-one perspective and new indicators for the evaluation of the interventions.

Internet use in Banyumas Regency is now increasingly diverse according to the demands of the needs. The development of communication technology raises various aspects that also develop. For example, the use of the internet for a traffic light control system so that it can be adjusted according to the settings and can be monitored in real time. In the development of communication technology, the term Internet of Things (IoT) emerged as the concept of extending the benefits of internet communication systems to give impulses to other systems. In other words, IoT is used as a communication for remote control and monitoring by utilizing an internet connection. The Internet of Things in the era is now being developed to create an intelligent system for the purposes of controlling various public needs until the concept of the smart city emerges. Basically, smart cities utilize internet connections for many purposes such as controlling CCTV, traffic lights, controlling arm robots in the industry and storing data in hospitals. If the system is carried out directly from the device to the central server, there will be a very long queue of data while the system created requires speed and accuracy of time so that a system is needed that allows sufficient data control and processing to be carried out on network edge users. Then fog Computing is used with the hope that the smart city system can work with small latency values ​​so that the system is more real-time in sending or receiving data.

The article reveals the content and explores the conceptual-categorical apparatus of the problem of the «smart city» formation on the territory of a large municipal entity. The classification of big municipalities, aimed at their services (communal, educational, medical, public) ‘smartization’, by type, is given. It is determined that smart cities are considered by the world scientific community from two positions: on the one hand, as objects of the spontaneous socio-economic movement, which cannot always be directed in a given strategic direction; on the other hand, as a managerial category – cities that effectively use all available information for better understanding and control of their functions and optimal use of resources available, including the potential of residents. A system of factors, the development of which is aimed at forming the foundations of a smart city, is given. The basis for developing such a system is the concept of sustainable development. Accordingly, the complex of the following factors influencing the ‘smartization’ of urban development is presented: technological (determines the level of development and public availability of digital technologies in urban services); human (creates a space for creativity, learning, obtaining and generating knowledge); economic (outlines the limits of economic capacity of the city, the coordination of economic tasks with social priorities and environmental needs); institutional (forms the basis for proper management of the city’s integrated development, promotes the development of the smart community and the attraction of intellectual capital). The criteria for meeting the goals of smart city management that outline the content and determine the directions of smart administration on the basis of sustainability are given; the factors of the formation of such a city (institutional, social, economic, technological) are presented and structured; accordingly, the concept of «smart city» is defined through the prism of institutional, social, economic, technological and integrated managerial approaches.
