However, the limited computational<br \/>\nresource in the edge cloud may result in the Quality<br \/>\nof Service degradation. In this paper, we address this issue by<br \/>\ncoordinating the heterogeneous cloud which includes the edge<br \/>\ncloud and the remote cloud. Considering the offloading of delaybounded<br \/>\ntasks, we study into the scheduling of heterogeneous<br \/>\ncloud in order to maximize the probability that tasks can have<br \/>\nthe delay requirements met. The problem formulation is proved<br \/>\nto be concave, and an optimal algorithm is proposed accordingly.<br \/>\nThe optimal policy with heterogeneous cloud is notably different<br \/>\nfrom the policy merely using the edge cloud. With only the edge<br \/>\ncloud, the system serves tasks with loose delay bounds and drops<br \/>\ntasks with stringent delay bounds when the traffic load is heavy.<br \/>\nHowever, with the heterogeneous cloud, tasks with stringent delay<br \/>\nbounds are offloaded to the edge cloud and tasks with loose delay<br \/>\nbounds are offloaded to the remote cloud. In numerical results,<br \/>\nthe probability that the delay bounds of tasks are satisfied can be<br \/>\nimproved by about 40% with the assistance of the remote cloud.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/wp-content\/uploads\/2017\/10\/\u8d75\u5929\u521dICC.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>Tianchu Zhao, Sheng Zhou, Xueying Guo, and Zhisheng Niu, <span class=\"papertitle\">Tasks scheduling and resource allocation in heterogeneous cloud for delay-bounded mobile edge computing\uff0c<\/span>, <span class=\"papersource\"> IEEE ICC 2017, Paris, May 21-25, 2017 <\/span><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","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\/3246"}],"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=3246"}],"version-history":[{"count":2,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/3246\/revisions"}],"predecessor-version":[{"id":3249,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/3246\/revisions\/3249"}],"wp:attachment":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3246"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3246"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3246"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
