A Hybrid Power-Saving Algorithm Based on Linear Growth in IEEE 802.16e

To support battery powered mobile broadband wireless access devices efficiently, IEEE 802.16e defines a sleep mode operation for conserving the power of mobile terminals. In this paper, a linear hybrid algorithm is proposed based on the adjustment of sleep window under circumstances of low service traffic, aiming for reducing the response time and energy consumption of mobile subscribe station (MSS). A performance evaluation for this algorithm is utilized by theoretical analysis, and the simulation result shows that the proposed algorithm improves the performance in power conservation.
