Energy of a mobile terminal (MT) is an important resource, so recent wireless network protocols like IEEE 802.11 and IEEE 802.16 include energy saving techniques. These protocols, however, have a problem in minimizing energy loss under varying traffic pattern and mobile environment. In this paper, we propose a sleep mode interval control algorithm that considers downlink traffic pattern and terminal mobility to maximize energy-efficiency. Through simulations, we show that our proposed algorithm improves energy saving and delay performance. There is no energy loss because it does not incur unnecessary cell searching in multi-cell environments.
