The world is moving towards modernization with the help of smart devices used in smart cities to make the whole lot intelligent and smart. These smart devices are extensively used in smart city and are capable of doing everything which one can do with the normal desktop computer. These smart devices like Smartphone have computational limitations are not able to store a large data to be used and collected in a smart city. In this paper, we propose a novel security architecture which first uses the Elliptic Curve Diffie Helman Key Exchange Algorithms to exchange the keys between the two low power devices (Smartphone). The keys are used to encrypt the large data (images and videos etc). The data is encrypted using the private keys of a device and then send to the cloud for safe storage. The data can be only accessed by the communicating device with the same key. The proposed security architecture enables these smart devices to store the huge data collected from the smart city to store on the cloud. If another device requests the same set of data, the keys can be shared secretly and the communicating device can be allowed to download the data directly from the cloud. This architecture relieves the Smartphone from the storage limitation and also enables it to communicate with faster speed and securely.

Urban Characteristics

Smart cities have attracted an extensive and emerging interest from both science and industry with an increasing number of international examples emerging from all over the world. However, despite the significant role that smart cities can play to deal with recent urban challenges, the concept has been being criticized for not being able to realize its potential and for being a vendor hype. This paper reviews different conceptualization, benchmarks and evaluations of the smart city concept. Eight different classes of smart city conceptualization models have been discovered, which structure the unified conceptualization model and concern smart city facilities (i.e., energy, water, IoT etc.), services (i.e., health, education etc.), governance, planning and management, architecture, data and people. Benchmarking though is still ambiguous and different perspectives are followed by the researchers that measure -and recently monitor- various factors, which somehow exceed typical technological or urban characteristics. This can be attributed to the broadness of the smart city concept. This paper sheds light to parameters that can be measured and controlled in an attempt to improve smart city potential and leaves space for corresponding future research. More specifically, smart city progress, local capacity, vulnerabilities for resilience and policy impact are only some of the variants that scholars pay attention to measure and control.

In response to the mounting criticism of emerging ‘smart cities’ strategies around the world, a number of individuals and institutions have attempted to pivot from discussions of smart cities towards a focus on ‘smart citizens’. While the smart citizen is most often seen as a kind of foil for those more stereotypically top-down, neoliberal, and repressive visions of the smart city that have been widely critiqued within the literature, this paper argues for an attention to the ‘actually existing smart citizen’, which plays a much messier and more ambivalent role in practice. This paper proposes the dual figures of ‘the general citizen’ and ‘the absent citizen’ as a heuristic for thinking about how the lines of inclusion and exclusion are drawn for citizens, both discursively and materially, in the actual making of the smart city. These figures are meant to highlight how the universal and unspecified figure of ‘the citizen’ is discursively deployed to justify smart city policies, while at the same time, actual citizens remain largely excluded from such decision and policy-making processes. Using a case study of Atlanta, Georgia and its ongoing smart cities initiatives, we argue that while the participation of citizens is crucial to any truly democratic mode of urban governance, the emerging discourse around the promise of smart citizenship fails to capture the realities of how citizens are actually discussed and enrolled in the making of these policies.

The paper analyzes the key steps taken by different cities worldwide and gathered into a clear step-by-step roadmap that can be useful for emerging smart cities. The Roadmap covers three main stages as we see them during the process of development: preparation, formation and spreading stages. We reveal how this is incorporated in the Ukrainian context. Our analysis of smart city solutions from all over the world (based on the BeeSmartCity database) showed that the tech component on its own is not enough to overcome urban challenges within different domains (environment, economy, government etc.), as we see each of the solutions has a human component involved in a form of knowledge generation and sharing, different forms of co-creation and partnership etc. Thus, ICTs are a required but not a sufficient element of building successful citizen-friendly and resilient cities.

Smart technologies are advancing, and smart cities can be made smarter by increasing the connectivity and interactions of humans, the environment, and smart devices. This paper discusses selective technologies that can potentially contribute to developing an intelligent environment and smarter cities. While the connectivity and efficiency of smart cities is important, the analysis of the impact of construction development and large projects in the city is crucial to decision and policy makers, before the project is approved. This raises the question of assessing the impact of a new infrastructure project on the community prior to its commencement—what type of technologies can potentially be used for creating a virtual representation of the city? How can a smart city be improved by utilizing these technologies? There are a wide range of technologies and applications available but understanding their function, interoperability, and compatibility with the community requires more discussion around system designs and architecture. These questions can be the basis of developing an agenda for further investigations. In particular, the need for advanced tools such as mobile scanners, Geospatial Artificial Intelligence, Unmanned Aerial Vehicles, Geospatial Augmented Reality apps, Light Detection, and Ranging in smart cities is discussed. In line with smart city technology development, this Special Issue includes eight accepted articles covering trending topics, which are briefly reviewed.

The Way

Culture is an important aspect of human civilization. Preserving and giving value to the cultural heritage of a region can pave the way for local as well as regional development. This includes tangible, intangible and the natural heritage of cities. It is necessary to develop a cultural infrastructure plan along with other aspects such as transportation, built, green and grey in frastructure. Cultural infrastructure refers to places where culture is experienced, participated in or showcased in. This includes the existing cultural heritage of a place as well as the planning of spaces for cultural stimulation and involvement. With the advent of fourth industrial revolution smart cities are gradually becoming the way of life across the world. The Smart City uses Information and Communication Technology (ICT) and Internet of Things (IoT) to effectively manage transportation, water services, waste disposal, energy and other community services. In this scenario it becomes imperative to have strategic infrastructure planning. Indian Government has recently launched the Smart City Mission in India and several smart city projects are underway across the country. It becomes necessar y in this context that Indian cities with their rich tradition and cultural heritage do not lose their unique identity in this process of transformation into smart cities. Even as smart city projects stress the need for heritage preservation there is a lot of ambiguity in how they can be integrated and used to advance urban intelligence. The technologies of the smart city have considerable potential to be used for the management and enhancement its cultural heritage and can help in the creation of a cultural infrastructure plan. This paper will examine the significance of cultural infrastructure in future cities and how it can be integrated into the city planning process of Indian cities through the study of relevant case studies from around the world.

Recent advances in experimental techniques have led to an enormous explosion of available data about protein–ligand complexes. To exploit the information that is hidden in these large data, collection tools for managing and accessing huge data collections are needed. This paper discusses databases for protein–ligand data which are accessibleviathe World Wide Web. A strong focus is placed on the ReLiBase database system which is a new three-dimensional database for storing and analysing structures of protein–ligand complexes currently deposited in the Brookhaven Protein Data Bank (PDB). ReLiBase contains efficient query tools for identifying and analysing ligands and protein–ligand complexes. Its application for structure-based drug design is illustrated.
