Abstract

In this paper, first, sleep-mode and wake-mode existing in the Medium Access Control (MAC) layer of IEEE 802.16 are introduced. Next cycles of sleep-mode are described. Finally optimum Tmin , which is obtained by improving the length of Tminpsilas window in sleep-mode of previous methods, is described. This method changes Tmin with the changes of network load to reach the best situation in power consumption. This method reduces the power consumption more than 14% for IEEE 802.16e mobile standard. The soundness of all information is proved by numerical analysis. Finally random digit test was used to evaluate the results of the method for power reduction.
