Advanced Human Centric 5GIoT in a Smart City: Requirements and Challenges. The concept of a smart city (SC) is developed on advanced informationcommunication technologies (ICT). The role of new 5G mobile wireless systems and Internet of Things (IoT) is discussed as essential for a successful SC infrastructure for interconnecting citizens in physical and virtual worlds. IoTbased smart cities can provide various kinds of services for citizens, including smart home, smart energy and meter systems, vehicular traffic and transportation, environmental pollution, smart health. The services are transforming cities by improving infrastructure and efficiency of the everyday activities. The huge development of smart devices, novel communication, computing and control technologies have paved the way for 5GIoT advancement. At the same time the final goal is to provide efficient humancentric communication. In this article smart cities infrastructure evolution is presented. Moreover, an overview of the role of 5GIoT including uptodate development is described. Later, we continue with humancentric 5GIoT in SC. Finally, in order to give future research directions several challenges are highlighted.

5G support for Industrial IoT Applicationsxe2x80x94 Challenges, Solutions, and Research gaps Industrial IoT has special communication requirements, including high reliability, low latency, flexibility, and security. These are instinctively provided by the 5G mobile technology, making it a successful candidate for supporting Industrial IoT (IIoT) scenarios. The aim of this paper is to identify current research challenges and solutions in relation to 5Genabled Industrial IoT, based on the initial requirements and promises of both domains. The methodology of the paper follows the steps of surveying stateofthe art, comparing results to identify further challenges, and drawing conclusions as lessons learned for each research domain. These areas include IIoT applications and their requirements; mobile edge cloud; backend performance tuning; network function virtualization; and security, blockchains for IIoT, Artificial Intelligence support for 5G, and private campus networks. Beside surveying the current challenges and solutions, the paper aims to provide meaningful comparisons for each of these areas (in relation to 5Genabled IIoT) to draw conclusions on current research gaps.
