CO2GREEN - Cooperative and Cognitive Techniques for Green Wireless Communications Print

 

Current 4G vision envisages higher data rates and multi-standard radio interfaces to provide users with a continuous seamless connection. The large number of foreseen devices coupled with the surge in power requirements for future emerging handsets raises significant challenges in terms of (i) reducing energy consumption and (ii) reducing the amount of electromagnetic radiation. Therefore, 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.
