Abstract
The exponential growth of cellular network traffic and flattening spectral efficiency are two of the biggest challenges facing beyond 5G wireless cellular networks. On the demand side, network traffic is exponentially growing and becoming much more diverse while on the supply side; the available spectrum and spectral efficiency are flattening out. One way for overcoming the problem of increasing per-user capacity and spectral efficiency is to make cells smaller and bring base stations closer to mobile hosts, thus reducing the number of users per cell and improving per link SNR. As a result, network deployments in beyond 4G wireless cellular networks will inevitably become extremely dense. The current architectures are however unable to support such extremely dense cellular and wireless deployments. One way to improve the cellular network architecture is to apply the fundamentals of software defined networking (SDN) to design layers of system and abstractions that simplifies the deployment and management of extremely dense wireless cellular networks. SDN can programmatically decouple network architectures from infrastructure, thus making it easier for deploying new applications and services, as well as for tuning network policy and performance. When the SDN theory is applied, base stations perform basic packet-processing functions under the command of a logically centralized controller. Thus, SDN enables distribution of data-plane rules over multiple, low-cost network switches, hence reducing the scalability of the packet gateway and enabling flexible handling of data traffic over the cellular network. In this talk a new architecture design for future wireless cellular networks will be explored.
