In this paper, we take a different look at it from energy saving point of view.  Specifically, we analyze the queuing behavior of AMC systems jointly with sleep mode where the wake-up process incurs time and energy cost. We formulate the optimization problem by jointly considering energy-efficiency, queuing delay and packet loss rate, and find the solution with cross-layer adjustment of the transmit power and the sleep threshold. Numerical results show that at low traffic range, when the power consumption of idle (no data transmission) mode is un-negligible, introducing sleep mode to the AMC system significantly improves the energy efficiency compared with non-sleep system. To achieve the energyefficiency gain, the system tends to use higher-order modulation by increasing transmit power, which also reduces the number of dropped packets.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"http:\/\/network.ee.tsinghua.edu.cn\/papers\/GongJ_ICC11.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>Jie Gong, Sheng Zhou, Zhisheng Niu, <span class=\"papertitle\">Queuing on Energy-Efficient Wireless Transmissions with Adaptive Modulation and Coding<\/span>, <span class=\"papersource\">Proc.
