One of the biggest challenges for future wireless systems is the need to limit the energy consumption of the battery-driven devices so as to prolong the operational times. Without new approaches for energy saving, there is a significant threat that the 4G mobile users will be searching for power outlets rather than network access, and becoming once again bound to a single location. This is the main motivation for CO2GREEN, where we aim to study cooperative and cognitive techniques to reduce the energy consumption of wireless communications. The main objectives of CO2GREEN are:

·         To define green metrics directly related to the delivered QoS and system spectral efficiency in order to measure the energy consumption at the component, node, and system/network levels.

·         To identify and define potential scenarios and use cases that may benefit from the use of the energy-efficient algorithms that will be proposed in the project.

·         To design, analyse and evaluate the potential benefits of cooperative techniques based on advanced short-range communications for the goal of power/battery lifetime saving of mobile wireless devices.

·         To design, analyse and evaluate minimum-energy consumption cognitive vertical handover procedures between different technologies in heterogeneous networks.

·         To validate the key research outcomes through large-scale computer-based simulation and real-life experimentation to test the applicability of CO2GREEN algorithms and protocols.
