Green and Energy Efficiency in Access Networks and Cloud Infrastructures

Over the last decade, there has been an increasing use of personal wireless devices, such as laptops, smartphones and tablets. The widespread availability of wireless access created an environment in which anywhere at anytime users access data and services hosted in cloud infrastructures. However, such wireless cloud network consumes a non-negligible amount of energy and generates a considerable amount of carbon, which is becoming a major concern in IT industry. In this context, we address the problem of reducing energy consumption and carbon footprint, as well as building green infrastructures in the two different parts of the wireless cloud: (i) wireless access networks including wireless mesh and campus networks, and (ii) data centers in a cloud infrastructure.
In the first part of the thesis, we present an energy-efficient framework for joint routing and link scheduling in multihop TDMA-based wireless networks. At a later stage, we extend this framework to cover campus networks using the emerging Software Defined Networking (SDN) paradigm. In the second part of the thesis, we address the problem of reducing energy consumption and carbon footprint of cloud infrastructures. Specifically, we propose optimization approaches for reducing the energy costs and carbon emissions of a cloud provider owning distributed infrastructures of data centers with variable electricity prices and carbon emissions in two different setups: the case of a cloud provider trying to reduce its carbon emissions and operational costs as well as the case where green constraints are specified by the cloud consumers in the form of Green SLAs.
