Endre Hegland Hjort Kure successfully defends his PhD
Mobile traffic is an essential part of today’s society, fueling people with entertainment such as Netflix, Youtube, and HBO. This leads to a near biannual doubling in traffic. The increased data usage comes with a cost, as ICT is becoming an ever-increasing source of pollution. It is, therefore, crucial to find methods that can curb the effect of exponential growth.
New technological advancements both in communications (5G and IoT) and in power (Smart Grid), may provide the necessary solutions. This work investigates the intersection between these technologies and how they may provide energy-efficient solutions. It is based on data collected from large scale measurements done in an operators’ network, and we show how differences in predictability in traffic and spectral-efficiency, can be leveraged on with different market models modeled with game theory. We refine established concepts for energy-efficiency such as offloading so that it can be used as the coming technology evolve. Furthermore, we scrutinize the use of renewable energy source both in terms of battery and the energy source itself. We investigate the assumption about green energy for communication networks and show that significant changes are needed for a green shift in power to occur.
The thesis is written within the field of communication systems. The work has been conducted at Simula Research Laboratory.
Prior to the defense, Kure presented his trial lecture Energy Efficiency in Future Mobile Network.
