One of the crucial challenges for future smart cities is to devise a citywide network infrastructure capable of effectively guaranteeing resource-efficient and reliable communications while managing the complexity of heterogeneous devices and access technologies. This edited book highlights and showcases state of the art research and innovations in 5G and beyond wireless communications technologies for connected smart cities. The main objectives of this work include the exploration of recent advances and application potentials of various communication technologies as promising enablers for future networked smart cities, the investigation of design-specific issues for the integration of different architectural components of smart cities, and addressing various challenges and identifying opportunities in terms of interoperability of potential solutions. The book is aimed at a core and interdisciplinary audience of engineers, researchers and professionals working on smart cities concepts and supporting the integration of next-generation information, communication, networking and sensing technologies. It will also be a very useful ancillary for advanced students and other professionals working on next-generation communication networks.

This book presents breakthroughs in the design of Wireless Energy Harvesting (WEH) networks. It bridges the gap between WEH through radio waves communications and power transfer, which have largely been designed separately. The authors present an overview of the RF-EHNs including system architecture and RF energy harvesting techniques and existing applications. They also cover the idea of WEH in novel discoveries of information, the theoretical bounds in WEH, wireless sensor networks, usage of modern channel coding together with WEH, energy efficient resource allocation mechanisms, distributed self-organized energy efficient designs, delay-energy trade-off, specific protocols for energy efficient communication designs, D2D communication and energy efficiency, cooperative wireless networks, and cognitive networks.

This book presents a comprehensive overview of Unmanned Arial Vehicles (UAV) and their integration of wireless communications and networks, including inherent challenges and open access concerns. The authors present the latest technologies associated with UAV-assisted wireless communications and networks by linking their association with 5G Wireless Networks.
