The mobile network is continuously evolving to fulfill subscribers requirements; however, there are still restrictions. In Chapter One, the authors propose a step-by-step revolution method and path for the mobile backhaul, backbone, core and service network adopting SDN, NFV and cloud technologies. this chapter is to cover the importance of TCP/IP protocol stack and its design on future mobile network, beyond 4G, with emphasis on the TCP which is used for transfer of the most user data for the most used Internet services nowadays (e.g., web-based services including social networking, file sharing, cloud computing, email and etc.). Chapter Two covers the importance of TCP/IP protocol stack and its design on future mobile network, beyond 4G, with emphasis on the TCP which is used for transfer of the most user data for the most used Internet services nowadays (e.g., web-based services including social networking, file sharing, cloud computing, email and etc.). Chapter Three presents several advanced mechanisms, concepts, performance analysis for QoS (Quality of Service) provisioning in future fifth generation (5G) terminals. Finally, the authors of Chapter Four describe the main components of Human Activity Recognition in wireless networks.
