A Hybrid Algorithm In Ieee 802.16e Sleep Mode Operation

In IEEE 802.16e system, mobile station (MS) is usually powered by battery. To save the limited power, IEEE 802.16e standard specifies sleep mode operation for power management. There are two significant performance metrics in sleep mode operation, one is energy consumption, the other is waiting delay. Our research is to shorten energy consumption and waiting delay. In this paper, a hybrid algorithm is proposed to reduce energy consumption and waiting delay. The proposed algorithm decreases the energy consumption and waiting delay efficiently, when data frame from base station (BS) to MS is in low traffic.
