#3 - Workshop on Energy Efficiency in Virtualised and Softwarized 5G Systems


The most recent results indicate 5G as a more holistic and radical network transformation to serve vertical services, where the connectivity solutions are tailored to the specific digital business case. The expected performance gains envisioned for and required by future communications networks are beginning to emerge through the consensus on fundamental new communication techniques. On this side, 5G introduces new radio technologies, such as massive Multiple Input Multiple Output (MIMO), millimetre waves, multi Radio Access Technology (multi-RAT), multi-tier architecture, and Device-to-Device (D2D) communication, to increase the data rate available to the end-user. This evolution will allow the same applications as we have today, but with much better performance. On the other side, 5G is expected to make possible the development of a paradigm shift in the network architecture, introducing technologies for the virtualization and softwarization of network function for achieving a flexible, scalable, efficient, and agile network. This revolutionary aspect of 5G implies new classes of application and business models that are not possible with today existing technologies. In both sides, the gains introduced by these technologies do not come for free. Energy consumption in the network infrastructure is no longer sustainable with the current approaches, and therefore has become a primary design goal of future wireless and wired communication networks. Given the complexity of heterogeneous technologies integrated in 5G for providing advanced services, a coordination and optimization of the technological resources in both radio access network and mobile core network is essential. This workshop 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 the target of energy efficiency.

Potential topics include but are not limited to the following:

- Energy-aware design and resource allocation in both 5G radio access and 5G mobile core networks

- Energy optimization in User association, power control, and channel selection in heterogeneous wireless networks

- Energy consumption analysis of caching systems in multi-tier architecture

- Energy consumption of architectures and operations of 5G Network Slicing

- Energy optimization in Software-Defined Networking (SDN) control in 5G

- Network Function Virtualization (NFV) orchestration for power savings in 5G

- SDN and NFV integration in radio access network and mobile core network

- Energy consumption, performance and orchestration of Containerized Virtual Network Functions (VNFs)

- Energy efficiency, QoS, economical, dependability, and security aspects in 5G

- Sustainability and energy-efficiency in integrated fronthaul-backhaul 5G network

- High energy-efficiency in the radio access interface in ultra-dense wireless networks

- Anticipatory mobile networking for power savings
