Abstract
Due to the fast development in communication technology and the emerging usage of Internet of Things (IoT) devices that produce a huge amount of data, the fifth generation (5G) mobile network is introduced to support this development. This mobile network can provide many advanced communication features in cellular phones. But unfortunately, this technology faces many challenges. One of its defective challenges is the management of a massive number of devices running different services, so Software Defined Network (SDN) is proposed as a key technology to overcome this drawback. SDN architecture provides higher flexibility, scalability, cost-effectiveness, and energy efficiency in 5G mobile networks. There are usually different architectures for the SDN control plane. We study some of these architectures, and we conciliate the usage of Logically Centralized-Physically Distributed (LC-PD) controller management architecture in 5G networks. This architecture enables providing higher throughput, and lower latency compared to other control plane architectures. In this paper, we focus on the demonstration that the LC-PD control plane architecture improves communication efficiency and the Quality of Services (QoS) of running internet services in the 5G mobile network. We use the Mininet-WIFI emulator in our simulation tests. Our conducted simulations show that employing the LC-PD control plane architecture in 5G networks enhances the QoS of Internet services compared to other SDN implementations.
Highlights
5G stands for fifth generation mobile technology
It’s the latest mobile wireless system iteration. This mobile wireless technology is more intelligent as it allows the interconnection of the entire world without limitations and adds more services and benefits to the world compared to fourth generation mobile technology (4G) [1]
We have studied a set of Software Defined Network (SDN) control plane architectures, which are namely, centralized control plane, distributed control plane, and Logically Centralized-Physically Distributed (LC-PD) control plane architectures [27], [28]
Summary
The 5G mobile systems model is an all-IP based model for wireless and mobile networks. The new generation wireless transmission technology will use beamforming techniques to effectively communicate information to user devices to prevent transmission energy wastage This technique helps in reducing the base station’s operating power. In SDN architecture, the Open Flow protocol is used to define data structures, messages, and procedures, to describe all the physical and logical elements within a data path and to ensure traditional functions of the control plane, such as modifying packets, managing the routing table, and managing the different flows This protocol supports the IPv6 features as access control, quality of service and tunneling through VPN and IPsec. There are usually many SDN control plane architectures, such as centralized, distributed and LC-PD control plane architecture, which all are emulated in Mininet-WIFI [47]
