IoT and Big Data Applications in Smart Cities: Recent Advances, Challenges, and Critical Issues

Abstract

The notion of smart cities has remained under evolution as its global implementations are challenged by numerous technological, economic, and governmental obstacles. Moreover, the synergy of the Internet of Things (IoT) and big data technologies could result in promising horizons in terms of smart city development which has not been explored yet. Thus, the current research aims to address the essence of smart cities. To this end, first, the concept of smart cities is briefly overviewed; then, their properties and specifications as well as generic architecture, compositions, and real-world implementations are addressed. Furthermore, possible challenges and opportunities in the field of smart cities are described. Numerous issues and challenges such as analytics and using big data in smart cities introduced in this study offers an enhancement in developing applications of the above-mentioned technologies. Hence, this study paves the way for future research on the issues and challenges of big data applications in smart cities.INDEX TERMS Big data, Internet of Things (IoT), smart city.

Innovation Trajectories for a Society 5.0

“…Urban growth is favored by the increasingly important use of data [41]. ICT and cloud computing [13,23,30,47] have the ability to use IoT technologies [19,28,46,48] and Big Data [24,28,49] to generate, process, analyze, and exploit urban data. In this way, it is easier to make decisions that accurately address the problems [25,45,50], issues, and challenges related to sustainability [51][52][53] and urbanization [15,16,54].…”

“…The Industry 4.0 and Society 5.0 Relationship Industry 4.0 (I4.0) has recently become a relevant phenomenon and is one of the most important international topics in both industry and academia today [17][18][19]. I4.0 can be understood as the combination of physical and digital technologies, such as artificial intelligence (AI) [13,20,21], cloud computing [22,23], Big Data [21,24], adaptive robotics [13], augmented and virtual realities [25], additive manufacturing [26], and the Internet of Things (IoT) [27,28].…”

Implementation of a Secure Storage Using Blockchain for PCA-FRF Sensor Data of Plate-Like Structures

“…For example, Big Data is one of the key contributions of Industry 4.0 that refers to large databases [53]. With the development in the application scope of computing tools, it is required to apply more precise systematic solutions for Big Data problems [54]. To this end, data-driven strategies based on data mining have been employed to obtain useful patterns from recorded sensor data [55].…”

The Use of Big Data Combined with Artificial Intelligence Neural Network Technology in Urban Spatial Evaluation System

“…Data mining, machine learning, and arti cial intelligence (AI) technology rise with the continuous progress of big data technology, which has brought breakthroughs to the development of science and technology [1]. In 2015, the State Council issued the Action Platform for Promoting the Development of Big Data, which proposed to promote the development and application of big data, accelerate the government's data sharing, and make an overall plan for the construction of big data infrastructure [2]. e Outline of the 13th Five-Year Plan for National Economic and Social Development of People's Republic of China issued in March 2016 proposed to take big data as a primary strategic resource to promote the development of big data comprehensively [3].…”
