However, it is very challenging to determine user association in a green WLAN while simultaneously considering several other factors, such as avoiding AP congestion and user migration constraints. Here, we study the energy\u2010efficient user association with congestion avoidance and migration constraint (EACM). First, we formulate the EACM problem as an integer linear programming (ILP) model, to minimize APs\u2019 overall energy consumption within a time interval while satisfying the following constraints: traffic demand, AP utilization threshold, and maximum number of demand node (DN) migrations allowed. Then, we propose an efficient migration\u2010constrained user reassociation algorithm, consisting of two steps. The first step removes<jats:italic>k<\/jats:italic>AP\u2010DN associations to eliminate AP congestion and turn off as many idle APs as possible. The second step reassociates these<jats:italic>k<\/jats:italic>DNs according to an energy efficiency strategy. Finally, we perform simulation experiments that validate our algorithm\u2019s effectiveness and efficiency.<\/jats:p>","DOI":"10.1155\/2018\/9596141","type":"journal-article","created":{"date-parts":[[2018,6,28]],"date-time":"2018-06-28T23:44:16Z","timestamp":1530229456000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Energy\u2010Efficient User Association with Congestion Avoidance and Migration Constraint in Green WLANs"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4437-0850","authenticated-orcid":false,"given":"Wenjia","family":"Wu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junzhou","family":"Luo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3156-9035","authenticated-orcid":false,"given":"Kai","family":"Dong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9691-8702","authenticated-orcid":false,"given":"Zhen","family":"Ling","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,6,28]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_10_1_2","DOI":"10.1016\/j.jnca.2017.09.002"},{"doi-asserted-by":"publisher","key":"e_1_2_10_2_2","DOI":"10.1016\/j.comcom.2015.10.007"},{"doi-asserted-by":"publisher","key":"e_1_2_10_3_2","DOI":"10.1109\/TNET.2010.2040087"},{"doi-asserted-by":"publisher","key":"e_1_2_10_4_2","DOI":"10.1109\/COMST.2014.2329505"},{"doi-asserted-by":"publisher","key":"e_1_2_10_5_2","DOI":"10.1109\/TCC.2015.2453966"},{"doi-asserted-by":"publisher","key":"e_1_2_10_6_2","DOI":"10.1016\/j.future.2017.08.057"},{"doi-asserted-by":"publisher","key":"e_1_2_10_7_2","DOI":"10.1007\/s11036-008-0123-8"},{"doi-asserted-by":"publisher","key":"e_1_2_10_8_2","DOI":"10.1016\/j.comcom.2012.06.011"},{"doi-asserted-by":"publisher","key":"e_1_2_10_9_2","DOI":"10.1016\/j.comnet.2014.10.033"},{"doi-asserted-by":"publisher","key":"e_1_2_10_10_2","DOI":"10.1109\/TMC.2014.2324582"},{"doi-asserted-by":"crossref","unstructured":"BejeranoY.
