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 factors in sleep mode operation, one is energy consumption, and the other is response delay. When MS wakes up by outgoing data frame from itself, only energy consumption is considered because of on response delay. And when MS wakes up by incoming data frame from base station (BS), both two factors should be considered. To get a full understanding of performance factors, a linear increase algorithm is proposed for an analytical mode. Then this paper shows the performance evaluation of power management.
