Abstract: Due to the promising mobility in IEEE802.16e, MS (mobile subscriber) is tightly constrained by battery capacity. So sleep mode mechanism becomes an important component for MS which can effectively manage the limited energy, and prolongs the use time of once-charged battery. This paper reviews 3 types of power saving classes of sleep mode of MS in IEEE802.16e, investigates the combinations of several power saving classes, and solves the problems of energy consumption and energy saving of MS at sleep mode. By system model simulation, it presents the methods of performance evaluation and enhancement of sleep mode based on variable parameter configurations.

Key words: IEEE802.16e, power saving class, periodic ranging, mean energy consumption, mean energy saving
