Most of the techniques applied to current mobile networks have been designed to maximize the performance metrics such as the throughput, QoS and reliability, paying no or little attention to the energy consumption of network devices. Moreover, except for the peak time, network devices are not utilized at their full capacity, and hence normally their required level of energy is much less than the supplied power at maximum level. In such an over-provisioning condition, the electrical power should be dynamically adjusted depending on the networking or traffic conditions. The energy saving gain of most of the green techniques is achieved usually at the cost of degradation of QoS, or say “performance compromise”. The tradeoff between the performance and the energy consumption should be carefully exploited.
