Enhanced Power Saving Mechanism to Maximize Unavailability Interval in the IEEE 802.16 Mobile WiMAX
Authors: , ,
Abstract: In this paper, an energy conservation mechanism to maximize the unavailability interval and to improve the energy efficiency for the Power Saving Class in WiMAX are proposed. The proposed method can be implemented in commercial fields and is fully compatible with the 802.16 standard. It provides a systematic way to adjust the start frame number of the first sleep window, one of the relevant parameters defined in power saving performance. The sleep cycle concept from IEEE 802.16m is applied to increase the unavailability interval. In summation to the computational complexity, simulations are studied to the procedure of the proposed algorithms. Our proposed model proves the unavailability interval ratio may increase up to 49.8% in some instance.
