Software-Defined Networking Applications in Wireless Networking
A review paper on the available options to enhance the already powerful Internet with the latest cutting edge concepts
Many parts of the Internet's classical design are currently carved in stone—a process known as ossification of the Internet—causing substantial challenges in IPv6 deployment and difficulty in employing IP multicast services. However, there are numerous reasons to further expand the Internet, such as enhancing intra-domain and inter-domain mapping for network uptime, providing end-to-end connectivity for user groups, and allowing dynamic QoS governance of network resources for new applications, data centres, cloud computing, and network virtualization.
The next-generation architecture for the Future Internet proposed the notion of Software-Defined Networking (SDN) to meet these needs. The separation and consolidation of the control plane from the network's forwarding components, as opposed to the dispersed control plane of existing networks, is at the heart of this new paradigm. This decoupling enables the deployment of control plane software components on computing platforms that are far more capable than conventional networking gear, e.g., routers, while safeguarding the information and privacy of the manufacturers of such equipment.
To meet these needs, this review paper surveys existing technologies as well as a wide range of contemporary and cutting-edge SDN initiatives, followed by an in-depth examination of the significant challenges in this field.
