Abstract

IEEE 802.16e Task Group has developed an IEEE 802.16 amendment supporting mobile terminals such as PDAs, phones, and laptops. The energy efficiency design is an important research issue for mobile terminals due to limited battery power of them. In this paper, we study the energy efficiency design of IEEE 802.16e. For the purpose of power efficient operation, there are two sleep mode operations related to normal data traffic in the current IEEE 802.16e specification. We propose analytical models of the two sleep mode operations and conduct their performance comparison in terms of the power consumption and the frame response time.
