We consider the users need to make the decision on<br \/>\nwhether to offload the tasks to the fog node nearby, based on<br \/>\nthe energy consumption and delay constraint. In particular, we<br \/>\nutilize queuing theory to bring a thorough study on the energy<br \/>\nconsumption and execution delay of the offloading process.<br \/>\nTwo queuing models are applied respectively to model the<br \/>\nexecution processes at the mobile device (MD) and fog node.<br \/>\nBased on the theoretical analysis, an energy efficient optimization<br \/>\nproblem is formulated with the objective to minimize the energy<br \/>\nconsumption subjects to execution delay constraints. In order to<br \/>\naddress the formulated problem, an alternating direction method<br \/>\nof multipliers (ADMM)-based distributed algorithm is proposed.<br \/>\nExtensive simulation studies are conducted to demonstrate the ef-<br \/>\nfectiveness of the proposed scheme and the superior performance<br \/>\nover the other existed schemes can be observed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/wp-content\/uploads\/2017\/12\/ZhengChang_GC17_final.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>Zhiyuan Jiang, Sheng Zhou, Zhisheng Niu, A Block Coordinated Update Method for Beam-Based Massive MIMO Downlink Scheduling Based on Statistical CSI, <span class=\"papersource\">APCC 2017, Dec. 11-13, Perth, 2017 <\/span><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[7],"tags":[99],"jetpack_sharing_enabled":true,"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/3717"}],"collection":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3717"}],"version-history":[{"count":0,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/3717\/revisions"}],"wp:attachment":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3717"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3717"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3717"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
