However, the random<br \/>\narrival of renewable energy brings new challenges to network<br \/>\nmanagement. Through adjusting the distribution of traffic load<br \/>\nin spatial domain, traffic shaping helps to balance the cell-level<br \/>\npower demand and supply, enhancing the utilization of<br \/>\nrenewable energy. In this paper, we investigate the power<br \/>\nsaving performance of traffic shaping in an analytical way.<br \/>\nSpecifically, an energy-optimal traffic shaping scheme (EOTS)<br \/>\nis devised for HCNs with EH, whereby the on-off state of the<br \/>\noff-grid small cell and the amount of offloading traffic are<br \/>\nadjusted dynamically, based on the statistic information of<br \/>\nenergy arrival and traffic load. Numerical results are given,<br \/>\nwhich show that EOTS scheme can significantly reduce the<br \/>\non-grid power consumption for the daily traffic and solar<br \/>\nenergy profiles, compared with the greedy method where users<br \/>\nare always offloaded to the off-grid small cell with priority.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/wp-content\/uploads\/2015\/12\/\u5f20\u73ca-Globecom.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>Shan Zhang, Sheng Zhou, Jie Gong, Zhisheng Niu, Ning Zhang, and Sherman Shen, <span class=\"papertitle\">Spatial Traffic Shaping in Heterogeneous Cellular Networks with Energy Harvesting<\/span>, <span class=\"papersource\">IEEE Globecom 2015, Dec. 2015<\/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\/2873"}],"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=2873"}],"version-history":[{"count":3,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/2873\/revisions"}],"predecessor-version":[{"id":2877,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/2873\/revisions\/2877"}],"wp:attachment":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2873"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2873"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2873"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
