New generation mobile communication systems like Long Term Evolution

(LTE) aim to deploy to customers a new mobile experience providing higher data

rates and lower latencies that can make wireless devices a great platform to run

a new whole set of services and applications, that was unimaginable just some

years ago. However, the energy demands of battery powered devices, needed

to support these new software applications substantially exceeds the capacity

of the actual battery technology. The development of new architectures and

procedures to build power-efficient and power-aware systems has become one of

the main purposes in the design of new generation wireless networks.
