Description
Summary:Saving energy is an important issue in IEEE 802.16e Broadband Wireless Access (BWA) networks. Sleep-mode operation in the IEEE 802.16e effectively saves energy consumption in order to extend life time of a Mobile Subscribe Station (MSS). However, frame response delay is another important performance metric. The constraint is that the sleep- mode operation can reduce consumed energy, but it must guarantee reasonable frame response delay. In this paper, we evaluate in details the effects of maximum sleep interval on energy consumption and on frame response delay of MSS in the sleep-mode operation. Furthermore, we propose a Delay Constraint Energy Saving (DCES) algorithm to quickly determine maximum sleep interval which minimizes energy consumption with frame response delay constraint. The validation of DCES algorithm suggests that the algorithm can provide a potential guidance to energy saving.
