Keynote Topic: Network Cloudification: SDN-NFV and 5G-MEC with Edge and Fog Computing
The second wave of cloud computing, named network cloudification, in the forms of SDN (Software Defined Networking), NFV (Network Function Virtualization), and 5G-MEC (Mobile Edge Computing), is to centralize and virtualize networking into data centers. It enables operators to offer NaaS (Networking as a Service) with much lower CAPEX and OPEX with larger flexibility because devices become simpler, the number of administrators is less, and service orchestration is easier. It turns parts of communications currently done in hardware into computing done in software. However, the host of these data centers would not be Google-like super data centers as they are too far away from subscribers. The latency requirement of 10ms and 1ms decentralizes cloud computing down to edge and fog computing with CORD (central offices re-architected as data centers) and cellular base stations for SDN-NFV and 5G-MEC, respectively. In this talk, we first argue why, where and when SDN, NFV, 5G-MEC would prevail, and then illustrate how to make it happen with OpenFlow, SC (Service Chaining), NSH (Network Service header), etc. Then we examine how latency requirement dominates this virtualization game by listing key questions to answer in resource allocation in the architectures of SDN, NFV, and 5G-MEC. Their answers are mostly unknown now but would benefit the architects and developers of OpenFlow switches, SDN controllers, SDN-NFV apps, NFV data centers, MEC-enabled base stations, and operator’s infrastructure in general.

Professor Rudolf Mathar
Keynote Topic: Elementary Channels for Quantization, Neural Networks and Molecular Information Exchange
Basic concepts of information theory, namely entropy, mutual information and capacity of channels, are universal tools which can also be applied to analyze information processing of biological systems. The main intention of this talk is to demonstrate the usefulness of information theoretic approaches to neural networks. We will briefly discuss biological neural networks and the functionality principles of neurons. Corresponding idealizing models will include linear, binary threshold, rectifying, censoring and sigmoid neurons. These can be interpreted as information channels, which opens the door to the field of information theory. The capacity and corresponding bounds will be derived providing interesting insight into the control and behavior of neurons. We will also investigate the underlying molecular information exchange by a Poissonian diffusion model.
Rudolf Mathar received the Ph.D. degree from RWTH Aachen University in 1981. He held lecturer positions with Augsburg University and the European Business School. In 1989, he joined the Faculty of Natural Sciences, RWTH Aachen University. He has held the International IBM Chair in computer science with Brussels Free University in 1999.

His research interests include information theory, mobile communication systems, particularly optimization, resource allocation, and access control. Recently he has initiated projects in the area of compressed sensing and data science.
Professor Jean Armstrong
Keynote Topic: Visible light communications: a solution to the spectrum crunch?
Standard white lighting LEDs unlike conventional forms of lighting can be modulated at megahertz frequencies. As a result every LED light has the potential to transmit high speed data. This is the basis of important new forms of visible light communications (VLC) and visible light positioning (VLP). This talk will outline the key findings of our research on VLC and VLP and that of other leading groups around the world. The huge potential of this emerging field to deliver very high speed data and accurate indoor positioning will be explained. The many research challenges that still have to be overcome to turn this potential into reality will be outlined. VLC, particularly one form called LiFi, has attracted a lot of media attention. This talk will separate the facts from the hype.

Dr Luca Chiaraviglio
Keynote Topic: Viability of 5G for Rural Communications
Nowadays, at least two billion people are experiencing a complete lack of wireless cellular coverage. Such users live in rural areas and low-income regions, where the network operators are not keen to invest, mainly due to high Capital Expenditure (CapEx) and Operational Expenditure (OpEx) costs, as well as the scarcity of electricity from the grid. We tackle this challenge by proposing a 5G network explicitly designed to serve rural and low-income areas. Our solution exploits Remote Radio Heads (RRHs) mounted on top of Unmanned Aerial Vehicles (UAVs), as well as Large Cells (LCs) to increase the coverage range. In addition, 5G-nodes are powered by solar panels and batteries. Preliminary results, obtained over three representative case studies (located in Italy, Cook Islands, and Zimbabwe) show that providing connectivity in rural and low-income areas by means of the proposed 5G architecture is feasible. At the same time, we also show that the monthly subscription fee paid by the users can be kept sufficiently low, e.g., less than 1 [EUR/month] in low-income areas, and less than 10 [EUR/month] in rural regions.
