| Abstract | In this paper, we propose a solution to the problem of energy consumption in wireless networks, which exploits the dynamic power management concept. Batterypowered user terminals can enter various sleep states depending on which part of the terminal circuitry is currently idle. Deeper sleep states imply a lower power consumption and a longer time overhead to return to the active state. Power management policies are typically used to control the state of operation of system components, i.e., to determine whether and when components should be turned off. We develop a framework that allows every user terminal to autonomously derive its optimal power management policy. By applying the optimal policy, users are able to minimize energy consumption while still meeting the required quality of service as channel propagation conditions and traffic load over the wireless channel vary. We focus on uplink data transfer and we consider mean packet delay and packet loss probability as targeted quality of service metrics. Results showing the trade-off between traffic quality of service and energy saving are presented. |
