Area Commun.,<br \/>\n<span class=\"paper_subtitle\">Published Date<\/span>:2015-2<br \/>\n<span class=\"paper_subtitle\">ABSTRACT<\/span><br \/>\nBase station (BS) sleeping operation is one of the<br \/>\neffective ways to save energy consumption of cellular networks,<br \/>\nbut it may lead to longer delay to the customers. The fundamental<br \/>\nquestion then arises: how much energy can be traded off by a<br \/>\ntolerable delay? In this paper, we characterize the fundamental<br \/>\ntradeoffs between total energy consumption and overall delay in<br \/>\na BS with sleep mode operations by queueing models. Here, the<br \/>\nBS total energy consumption includes not only the transmitting<br \/>\npower but also basic power (for baseband processing, power<br \/>\namplifier, etc) and switch-over power of the BS working mode,<br \/>\nand the overall delay includes not only transmission delay but<br \/>\nalso queueing delay. Specifically, the BS is modeled as an M\/G\/1<br \/>\nvacation queue with setup and close-down times, where the BS<br \/>\nenters sleep mode if no customers arrive during the close-down<br \/>\n(hysteretic) time after the queue becomes empty. When asleep, the<br \/>\nBS stays in sleep mode until the queue builds up to N customers<br \/>\nduring the sleep period (N-Policy). Several closed-form formulas<br \/>\nare derived to demonstrate the tradeoffs between the energy<br \/>\nconsumption and the mean delay for different wake-up policies by<br \/>\nchanging the close-down time, setup time, and the parameter N.<br \/>\nIt is shown that the relationship between the energy consumption<br \/>\nand the mean delay is linear in terms of mean close-down time,<br \/>\nbut non-linear in terms of N. The explicit relationship between<br \/>\ntotal power consumption and average delay with varying service<br \/>\nrate is also analyzed theoretically, indicating that sacrificing<br \/>\ndelay cannot always be traded off for energy saving. In other<br \/>\nwords, larger N may lead to lower energy consumption, but there<br \/>\nexists an optimal N* that minimizes the mean delay and energy<br \/>\nconsumption at the same time. We also investigate the maximum<br \/>\ndelay (delay bound) for certain percentage of service and find that<br \/>\nthe delay bound is nearly linear in mean delay in the cases tested.<br \/>\nTherefore, similar tradeoffs exist between energy consumption<br \/>\nand the delay bound. In summary, the closed-form energy-delay<br \/>\ntradeoffs cast light on designing BS sleeping and wake-up control<br \/>\npolicies which aim to save energy while maintaining acceptable<br \/>\nquality of service.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/wp-content\/uploads\/2015\/02\/NiuZhisheng_JSAC_ET2.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-117\" title=\"pdf\" src=\"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/wp-content\/uploads\/2010\/08\/pdf.gif\"alt=\"\" width=\"95\" height=\"50\" \/><\/a>Zhisheng Niu, Xueying Guo, Sheng Zhou, P.
