An Adaptive QoS-Guranteed Power Saving Mechanism for Mobile WiMAX

Abstract

WiMAX is used to solve “last mile” in network deployment. Due to the limited power of mobile devices, power saving becomes a key issue for mobile applications. Though plenty of efforts have been proposed to save power, the problems are partially solved. In this paper, an adaptive power saving mechanism with low response delay is proposed. In our design, parameters related to power management are dynamically set according to current network traffic. As shown in the simulation results, the power efficiency and response delay of the proposed method are better than those of the well-known power saving mechanisms.
