To reduce this gap, this paper describes an optimization algorithm\u2014based on evolutionary strategy\u2014created as an aid for decision\u2010making prior to the real deployment of wireless LANs. The developed algorithm allows automating the design process, traditionally handmade by network technicians, in order to save time and cost by improving the WLAN arrangement. To this end, we implemented a multiobjective genetic algorithm (MOGA) with the purpose of meeting two simultaneous design objectives, namely, to minimize the number of APs while maximizing the coverage signal over a whole planning area. Such approach provides efficient and scalable solutions closer to the best network design, so that we integrated the developed algorithm into an engineering tool with the goal of modelling the behavior of WLANs in ICT infrastructures. Called WiFiSim, it allows the investigation of various complex issues concerning the design of IEEE 802.11\u2010based WLANs, thereby facilitating design of the study and design and optimal deployment of wireless LANs through complete modelling software. As a result, we comparatively evaluated three target applications considering small, medium, and large scenarios with a previous approach developed, a monoobjective genetic algorithm.<\/jats:p>","DOI":"10.1155\/2018\/7560717","type":"journal-article","created":{"date-parts":[[2018,3,26]],"date-time":"2018-03-26T23:31:40Z","timestamp":1522107100000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Optimal Modeling of Wireless LANs: A Decision\u2010Making Multiobjective Approach"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9387-3892","authenticated-orcid":false,"given":"Tom\u00e1s de Jes\u00fas","family":"Mateo Sanguino","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jhon Carlos","family":"Mendoza Betancourt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,3,26]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4419-6111-2_1"},{"volume-title":"CCNA Wireless 640-722 Official Cert Guide","year":"2014","author":"Hucaby D.","key":"e_1_2_9_2_2"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2007.01.025"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-40162-1_31"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.compedu.2013.08.015"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/TE.2012.2201157"},{"key":"e_1_2_9_7_2","unstructured":"VasudevanS.
