To investigate load optimizing from a perspective of system utilization maximization more than just offloading to improve APs\u2019 usage, a utility maximization (UTMAX) optimization model and an ASRAO algorithm based on generalized Benders Decomposition are proposed in this paper. UTMAX is to maximize the sum of logarithmic utility functions of user data rate by jointly optimizing user association and resource allocation. To maintain the flexibility of resource allocation, a parameter <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mi>\u03b2<\/mml:mi><\/mml:mrow><\/mml:math> is added to the utility function, where smaller <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mrow><mml:mi mathvariant=\"normal\">\u03b2<\/mml:mi><\/mml:mrow><\/mml:math> means more resources can be allocated to edge users. As a result, it reflects a tradeoff between improvements in user throughput fairness and system total throughput. UTMAX turns out to be a mixed integer nonlinear programming, which is intractable intuitively. So ASRAO is proposed to solve it optimally and effectively, and an optional phase for expediting ASRAO is proposed by using relaxation and approximation techniques, which reduces nearly 10% iterations and time needed by normal ASRAO from simulation results. The results also show UTMAX\u2019s good effects on improving WLAN usage and edge user throughput.<\/jats:p>","DOI":"10.1155\/2016\/6929575","type":"journal-article","created":{"date-parts":[[2016,11,6]],"date-time":"2016-11-06T16:01:18Z","timestamp":1478448078000},"page":"1-14","source":"Crossref","is-referenced-by-count":0,"title":["Utility Maximization for Load Optimization in Cellular\/WLAN Interworking Network Based on Generalized Benders Decomposition"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4158-6517","authenticated-orcid":true,"given":"Fanqin","family":"Zhou","sequence":"first","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3494-5590","authenticated-orcid":true,"given":"Lei","family":"Feng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0402-5390","authenticated-orcid":true,"given":"Peng","family":"Yu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3852-1007","authenticated-orcid":true,"given":"Wenjing","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China"}]},{"given":"Luoming","family":"Meng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China"}]}],"member":"311","reference":[{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/comst.2014.2369742"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/4868479"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2013.070113.130730"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2013.040413.120676"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1007\/BF01386316"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1007\/bf00934810"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1007\/s10107-004-0570-3"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/6929575.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/6929575.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/6929575.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,11,6]],"date-time":"2016-11-06T16:01:21Z","timestamp":1478448081000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/misy\/2016\/6929575\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":7,"alternative-id":["6929575","6929575"],"URL":"https:\/\/doi.org\/10.1155\/2016\/6929575","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"type":"print","value":"1574-017X"},{"type":"electronic","value":"1875-905X"}],"subject":[],"published":{"date-parts":[[2016]]}}}
