Project: Cognitive radio and Cooperative strategies for POWER saving in multi-standard wireless devices

Acronym: C2POWER
Main Objective:
The promise of a truly mobile experience is to have the freedom to roam around anywhere and not be bound to a single location. However, the energy required to keep mobile devices connected to the network over extended periods of time quickly dissipates. In fact, the operational time, has been identified as the number one criteria by the majority of the consumers purchasing a mobile device. Moreover, concern about exhausting battery lifetime is also one of the main reasons why users do not opt to use advanced multimedia services on their mobiles more frequently.

To avoid the foreseen 4G “energy trap” C2POWER project will investigate, develop and demonstrate how cognition and cooperative strategies can be extended to decrease the overall energy consumption of mobile devices while still enabling the required performance in terms of QoS.

In particular, C2POWER will investigate two complementary techniques to increase power efficiency at the wireless interface of handsets:

* Cooperative power saving strategies between neighbouring nodes using low power short range communications;
* Cognitive handover mechanisms to select the Radio Access Technology which has the lowest energy demand in heterogeneous environments.
