Beyond6G- Consensus Traffic Management in CRN, Applications, Architecture and key Challenges

5G CR network communication covered several features missed in 4G communication functions in several developed countries. Another concept of CR network communication is 6G, with throughout provision of Artificial Intelligence is supposed to be deployed till 2030. Beyond 5G, it covered few fundamental issues that require improved and maximum capacity, low latency, maximum data transfer rate, and progressed Quality of services compare with 5G CR network system. This work put a light on future 6G CR network and CR network architecture. Studied advancing technologies like wireless optical technology, cell-free communication, Artificial Intelligence, terahertz communication, 3D network, free space optic network, unnamed air vehicle, blockchain, integration of CR network communication, backhaul network integration, communication and sensing integration, and dynamic network sharing which may help in developing 6G architecture in assuring the Quality of services. We studied predictable technologies and applications for 6G CR network communication. We also discussed potential challenges in 6G CR network.
