The Role of 5G and IoT in Smart Cities

Smart cities, one of the key application areas of 5G and IoT technologies, have at their core the goal of improving quality of life, creating collaborative solutions, and addressing resource constraints. Examples of some of the many services integrated into the network of a typical smart city are related to smart health, smart transportation, smart buildings, smart hotels, smart industry, smart universities, etc. The new era of wireless mobile telecommunication technology and the IoT ecosystem is driving the opportunities for smart cities to not only solve existing problems but also create new services and functionalities that are out of the box and invisible to the end user. The main objective of this paper is to explore the role of 5G and IoT in smart cities. The market environment, key business developments, and trends related to the key smart cities’ enablers, IoT and 5G, are presented. An in-depth literature review followed by a discussion is substantiated with synthesised research findings on the current development, 5G coverage, use and deployment of IoT in smart cities, and forecasting the evolution of its application in smart cities. &nbs

Exploration of a New Model of "Highway + Tourism" Development from the Perspective of 5G——Taking the Yichang Road Tourism Economic Belt as an Example

The innovation of 5G technology is the characteristics of the progress and development of the times, now Yibin City Yichang Road construction has been basically perfect, along the way tourism in this network era and the epidemic epidemic intersection can be described as ready to go, in the typical mode of "highway + tourism", with the help of 5G advantages, Yichang Road tourism economic belt innovation into "5G + highway + tourist attractions + tourism services" integrated tourism comprehensive development model, adapt to the development of the times and the diversification characteristics of tourists, explore new directions of industry development, draw a new main line for high-quality tourism development. 5G is a mobile communication technology, but also a trend of future development, in the development of Yibin Yichang Road tourism, seize the new opportunities of 5G mobile communication development, rely on the "Internet of Things", "cloud computing" and "smart city" common development, combined with the current situation, with the help of "highway + tourism" typical model, strive to explore a new development model for Yichang Road tourism economy

A privacy-preserving user authentication mechanism for smart city mobile apps

In the dawn of the 5G era, the advances in mobile communications have created a suitable environment for the emergence of a wide spectrum of Smart City mobile applications that will play a significant role towards the improvement of citizens' life quality in the upcoming years. It is expected that Smart City mobile applications will allow citizens to access numerous and diverse services, provided by third-party Service Providers, through their mobile devices (e.g., smartphones). However, in order for the emerging Smart City mobile applications to gain the trust of all involved stakeholders and reach their full potential in the 5G market, many security and privacy concerns should be addressed in advance. Towards this direction, this paper proposes a privacy-preserving user authentication mechanism, developed in the context of the Mobilizador5G project, in order to: (a) provide mobile users with efficient and effective means to authenticate towards Service Providers, while preventing user identification and tracking; (b) allow anonymity revocation in case of user misbehavior; (c) avoid multiple user profiles creation on the Service Provider side; and (d) enable easy integration in current mobile application implementations

Representing human mobility patterns in urban spaces

Human mobility is important in understanding urban spaces. Citizens interact with urban spaces using the available infrastructures, not just in the mobility sector but in public services, and in Information and Communications Technology (ICT) services, that simultaneously record their footprints. Besides, the number of mobile users is increasing very rapidly in the Internet of Things (IoT) era. These additional devices will produce a great amount of data and create new big challenges for network infrastructure. Because of this new connectivity platform, and the fast growth of wireless communication, it’s important to discuss the arrival of 5G systems. They will have a large impact on coverage, spectral efficiency, data rate of global mobile traffic, and IoT devices, and in turn it will be possible to analyze the lifestyle and understand the mobility of people, such as the most frequently visited urban spaces. Therefore, this paper is relevant in the context of smart cities and will allow for an easy connection between citizens and technology innovation hub, acquiring detailed data on human movements. Based on the analysis of generated data we try to widen this view and present an integrated approach to the analysis of human mobility using LinkNYC kiosks and 311 Service Requests in New York city

Managing nonuniformities and uncertainties in vehicle-oriented sensor data over next generation networks

Detailed and accurate vehicle-oriented sensor data is considered fundamental for efficient vehicle-to-everything V2X communication applications, especially in the upcoming highly heterogeneous, brisk and agile 5G networking era. Information retrieval, transfer and manipulation in real-time offers a small margin for erratic behavior, regardless of its root cause. This paper presents a method for managing nonuniformities and uncertainties found on datasets, based on an elaborate Matrix Completion technique, with superior performance in three distinct cases of vehicle-related sensor data, collected under real driving conditions. Our approach appears capable of handling sensing and communication irregularities, minimizing at the same time the storage and transmission requirements of Multi-access Edge Computing applications
