Souvik Roy, Chandi Pani · Advances in Wireless and Mobile Communications · 2021
The scenario of modern day internet communication system has been changed drastically.Billions of hyper connected devices carrying huge amount of information on either side.Next generation devices are much of IoT enabled and automotive in nature demands much higher data speed with low latency.In addition, these modern tech shifts need such a network, which is much flexible, radio resource effective, dynamic, programmable and simplified in nature.Several exertion has been carried out to establish a next generation network architecture, which are operator centric.5G technology deployment with full IP connectivity has been done in some countries but not flawless.Evolved Packet Core (EPC) associated with 3GPP release 15 has been orchestrated.In this context, we will inspect a decentralized 5G architecture, which is accredited with Software Defined Networking (SDN) and Virtualized Network Function (VNF).A cloud based distributed architecture with dispute is manifested.A comprehensive study of research work so far has been accumulated in the context of architecture, network management and functionality.
