Due to the technology advancements, in recent days, most of the wireless devices are connected to machines (IoT) rather than human being, will lead to the growth in Smart Cities, Smart Homes, Smart Vehicles etc. Hence, the future customers will request for higher capacity, higher data rate with global connectivity. Hence, 5G and B5G networks encounter fundamental challenges for peer-to-peer IoT communications, including automated vehicle, robotic and other automatic systems, and computing infrastructures. Therefore Internet-of-Everything (IoE), integration of everything in a single hub is the related development. Other challenges predicted for future networks are to handle Ultra-dense cell networks, Reconfigurable Hardware, Networked VLC, Networking Intelligence and technological developments to empower the users with 100% Immersive Experiences.
