Orchestration and Control in Software-Defined 5G Radio Access and Core Networks

Call for Papers

The fifth generation (5G) of cellular networks aims to revolutionize the world of wireless communication. 5G will be characterized by ubiquitous connectivity, extremely low latency, and very high-speed data transfer. These characteristics will enable the use of 5G in a very broad set of application scenarios: from pervasive video to high user mobility; from broadband access everywhere to lifeline communications; from massive Internet of Things to broadcast-like services; from tactile Internet to ultrareliable communications. For enabling this variety of applications, ambitious improvements with respect to 4G are needed: 10-100 times more connected devices; 1000 times higher mobile data volume per area; 10-100 times higher data rate; 1 ms latency; 99.99% availability; 10 times less energy consumption; 5 times less network management operation expenses.

For achieving the challenging objectives of 5G, the research community has been working on several research directions: the radio access network for an enhanced mobile broadband and virtualizing and softwarizing the network infrastructure for a flexible, scalable, efficient, and agile operation. In this context, 5G will include heterogeneous technologies, which need to be integrated in order to provide advanced services. Emerging networking paradigm, such as Software-Defined Networking (SDN) and Network Function Virtualization (NFV), will enable the coordination and optimization of the technological resources in both radio access network and mobile core network. This special issue aims to attract the research community that is currently working on approaches for the orchestration and control of the network for the 5G radio and core resources with different objectives, such as energy efficiency, Quality of Service (QoS), economical cost reduction, dependability, and security.

Potential topics include but are not limited to the following:

  • Design and resource allocation in both radio access and mobile core networks
  • User association, power control, and channel selection in heterogeneous wireless networks
  • Caching in multitier architecture
  • Architecture and operation of 5G Network Slicing
  • SDN control and orchestration of Virtual Network Functions (VNFs) in 5G
  • SDN and NFV integration in radio access network and mobile core network
  • Performance and orchestration of containerized VNFs
  • Dynamic load-balancing scheme for the data and control plane of 5G
  • Cost-efficient and fast failure recovery for the data plane of 5G
  • Primary-backup replication with traffic adaptivity for the control plane of 5G
  • Path computation algorithms in multilayer multidomain T-SDN networks for 5G
