An Adaptive Power Saving Strategies based on Cross-layer Design in IEEE 802.16e

To enhance the power efficiency of broadband wireless access devices based on battery power, an adaptive power saving strategies based on cross-layer design is proposed for IEEE 802.16e sleep-mode operation. In this paper, the authors evaluate performance of the power-saving mechanism based on sleep mode in IEEE 802.16e mobile Worldwide Interoperability for Microwave Access (WiMAX) system, which is based on time scheme to trigger transition from awake mode to sleep mode and a sleep window to next sleep window.
