Delay analysis for sleep-based power saving mechanisms with downlink and uplink traffic

Abstract—In wireless networks, sleep-based power saving mechanisms can reduce the energy consumption at the expense of additional packet delay. This paper proposes a queueing model to analyze the packet queueing delay. Compared with the existing models which consider downlink traffic only, both downlink and uplink traffic are considered in the analysis. Index Terms—Power saving, sleep, delay analysis. I
