Power saving scheme based on joint control of bufferthreshold and timer in binary exponential sleep mode

We propose a new power saving scheme based on a buffer-threshold and timer in wireless packet networks. In a standard sleep mode operation with a binary exponential algorithm, a mobile station (MS) can begin a wake period if it is aware of the existence of its own downlink packets during a listening interval. In a light traffic environment, this conventional standard operation consumes a considerable amount of power to switch modes (sleep/listen/wake). To solve this problem, in this paper, a new power saving scheme based on Joint Control of Buffer-threshold and Timer (JCBT) is proposed. To see the performance behavior of the JCBT scheme, we consider the total power consumption per unit time and the average packet transfer delay as performance measures. Based on the performance measures, we March 13, 2012 DRAFT
