The framework exploits historical data (i.e., per-macro-cell load curves) to select a set of candidate switch-on\/switch-off instants of microcells, assuming a<jats:italic> limited <\/jats:italic>number of state changes is allowed in a day. The switching instants are instead determined<jats:italic> online<\/jats:italic>, by taking into account the actual traffic as well as the load curves. Moreover, intercell interference is fully accounted for. Our simulations show that this framework allows a multicell network to sustain peak-hour load when necessary and to reconfigure to a minimum coverage baseline whenever feasible, thus saving power (up to 25% in our scenarios). Moreover, the framework is<jats:italic> robust<\/jats:italic>, meaning that deviations of the actual traffic with respect to the prediction offered by the load curves can easily be handled.<\/jats:p>","DOI":"10.1155\/2017\/2495934","type":"journal-article","created":{"date-parts":[[2017,6,7]],"date-time":"2017-06-07T17:03:22Z","timestamp":1496855002000},"page":"1-17","source":"Crossref","is-referenced-by-count":1,"title":["A Practical Framework for Energy-Efficient Node Activation in Heterogeneous LTE Networks"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0629-1078","authenticated-orcid":true,"given":"Antonio","family":"Virdis","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, University of Pisa, Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni","family":"Stea","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, University of Pisa, Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dario","family":"Sabella","sequence":"additional","affiliation":[{"name":"Intel Deutschland GmbH, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Caretti","sequence":"additional","affiliation":[{"name":"Telecom Italia, Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"5","doi-asserted-by":"publisher","DOI":"10.1364\/OE.20.00B513"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2014.02.001"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2014.07.014"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2015.09.006"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2014.2329505"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2011.5783986"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2013.042313.00226"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2012.020212.00049"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2011.6056692"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2013.07.016"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1186\/1687-1499-2012-248"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2013.071613.122092"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2016.2536106"},{"journal-title":"IEEE\/ACM Transactions on Networking","year":"2017","key":"30"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2016.2602824"},{"journal-title":"NETWORKING 2012 Workshops","year":"2012","key":"26"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-27568-0_17"},{"volume-title":"Link level simulator for LTE downlink","year":"2009","key":"32"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2017\/2495934.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2017\/2495934.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2017\/2495934.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,7]],"date-time":"2017-06-07T17:03:23Z","timestamp":1496855003000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/misy\/2017\/2495934\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":18,"alternative-id":["2495934","2495934"],"URL":"https:\/\/doi.org\/10.1155\/2017\/2495934","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"type":"print","value":"1574-017X"},{"type":"electronic","value":"1875-905X"}],"subject":[],"published":{"date-parts":[[2017]]}}}
