Cloud computing is a key trend in computing and networking. Now diffused among end-users devices in mobile and wireline networks, the cloud is becoming the "fog". This book presents frameworks and schemes that use devices from end-users or near-users to carry out storage, communication, computation and control in the network. These novel approaches support the Internet of Things, the efficient provision of heterogeneous 5G mobile services, as well as emerging applications over future wireless network architectures. Elaborating on the emerging mobile networking paradigms for the 2020 5G timeframe, this book presents new connectivity services that are highly scalable and programmable in terms of speed, capacity, security, reliability, availability, latency and impact on battery life. Finally, the book discusses recent and new developments, prompting future directions on the theories, practices, standards and strategies related to 5G mobile systems.

The incredible growth in the development and use of wireless communication technologies has led to research in both academia and industry on artificial intelligence (AI) methods that enable intelligent technologies, smarter services and applications, business processes and social interactions to satisfy future requirements. AI mechanisms are being exploited in smart intelligent network applications to provide insights from collected data by identifying patterns and allowing operational predictions with higher accuracy in smaller time periods. The future of AI-powered wireless networking infrastructures depends on finding effective solutions to a number of technical challenges that such paradigms introduce, including better intelligent sensor capabilities, smarter big data analytics, automated remote data management, as well as open and secure processes.
