Abstract
In wireless telecommunication networks, there is a strong interest in energy efficiency. Sleep-mode mechanisms, which temporarily switch off mobile devices or base stations, are popular means to attain this goal. We look at the performance of different sleep-mode mechanisms with large-deviations tools. These allow us to look at a general multi-user model, for which we obtain a sample path large-deviations principle. As the system equations exhibit discontinuous boundaries, there are some mathematical obstacles to overcome. The results shed light on the trade-off between buffer overflow and energy consumption. We illustrate the results in scenarios with one and multiple mobile stations.
