However, current resource reallocation solution seldom considers the stability of virtual machine (VM) placement pattern. Varied workloads of applications would lead to frequent resource reconfiguration requirements due to repeated appearance of hot nodes. In this paper, several algorithms for VM placement (multiobjective genetic algorithm (MOGA), power-aware multiobjective genetic algorithm (pMOGA), and enhanced power-aware multiobjective genetic algorithm (EpMOGA)) are presented to improve stability of VM placement pattern with less migration overhead. The energy consumption is also considered. A type-matching controller is designed to improve evolution process. Nondominated sorting genetic algorithm II (NSGAII) is used to select new generations during evolution process. Our simulation results demonstrate that these algorithms all provide resource reallocation solutions with long stabilization time of nodes. pMOGA and EpMOGA also better balance the relationship of stabilization and energy efficiency by adding number of active nodes as one of optimal objectives. Type-matching controller makes EpMOGA superior to pMOGA.<\/jats:p>","DOI":"10.1155\/2016\/4859862","type":"journal-article","created":{"date-parts":[[2016,12,29]],"date-time":"2016-12-29T16:03:54Z","timestamp":1483027434000},"page":"1-9","source":"Crossref","is-referenced-by-count":4,"title":["Power-Aware Resource Reconfiguration Using Genetic Algorithm in Cloud Computing"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8699-0524","authenticated-orcid":true,"given":"Li","family":"Deng","sequence":"first","affiliation":[{"name":"College of Computer Science and Technology, Wuhan University of Science and Technology, Wuhan 430065, China"},{"name":"Hubei Province Key Laboratory of Intelligent Information Processing and Real-Time Industrial System, Wuhan, China"}]},{"given":"Yang","family":"Li","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Wuhan University of Science and Technology, Wuhan 430065, China"},{"name":"Hubei Province Key Laboratory of Intelligent Information Processing and Real-Time Industrial System, Wuhan, China"}]},{"given":"Li","family":"Yao","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Wuhan University of Science and Technology, Wuhan 430065, China"},{"name":"Hubei Province Key Laboratory of Intelligent Information Processing and Real-Time Industrial System, Wuhan, China"}]},{"given":"Yu","family":"Jin","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Wuhan University of Science and Technology, Wuhan 430065, China"},{"name":"Hubei Province Key Laboratory of Intelligent Information Processing and Real-Time Industrial System, Wuhan, China"}]},{"given":"Jinguang","family":"Gu","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Wuhan University of Science and Technology, Wuhan 430065, China"},{"name":"Hubei Province Key Laboratory of Intelligent Information Processing and Real-Time Industrial System, Wuhan, China"}]}],"member":"311","reference":[{"issue":"3","key":"2","volume":"16","year":"2016","journal-title":"ACM Transactions on Internet Technology"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2013.09.031"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TCC.2016.2564403"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1145\/2788397"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1145\/2742488"},{"issue":"2","key":"14","volume":"16","year":"2016","journal-title":"ACM Transactions on Embedded Computing Systems"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.3724\/sp.j.1016.2011.02253"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/TNET.2015.2389270"},{"issue":"2","key":"18","volume":"34","year":"2016","journal-title":"ACM Transactions on Computer Systems"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1145\/2843889"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1145\/2701429"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/tpds.2014.2325564"},{"issue":"1","key":"22","volume":"2","year":"2015","journal-title":"ACM Transactions on Parallel Computing"},{"issue":"4","key":"23","volume":"1","year":"2016","journal-title":"ACM Transactions on Modeling and Performance Evaluation of Computing Systems"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1145\/2983642"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1145\/2990197"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1109\/4235.996017"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4859862.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4859862.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4859862.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,12,29]],"date-time":"2016-12-29T16:04:01Z","timestamp":1483027441000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/misy\/2016\/4859862\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":17,"alternative-id":["4859862","4859862"],"URL":"https:\/\/doi.org\/10.1155\/2016\/4859862","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"type":"print","value":"1574-017X"},{"type":"electronic","value":"1875-905X"}],"subject":[],"published":{"date-parts":[[2016]]}}}
