A Software Product Line approach would be very appropriate to express the different requirements of either devices or applications in terms of commonalities and variabilities defining a family of AmI middleware platforms. One of the main services that an AmI middleware has to provide is the management of the context. There are several properties that affect the current context of the middleware: device constraints, applications restrictions, user preferences and runtime environment state. A feature model will help to specify and reason about the different middleware configurations tailored to either devices or application constraints. This feature model will enable different versions of a specific middleware for AmI to be generated, with the minimum number of services being required by the specific context properties.<\/jats:p>","DOI":"10.3233\/978-1-58603-946-2-82","type":"book-chapter","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T18:02:07Z","timestamp":1739988127000},"source":"Crossref","is-referenced-by-count":0,"title":["Variability in AmI Middleware Context-Awareness Service"],"prefix":"10.3233","author":[{"family":"Fuentes Lidia","sequence":"additional","affiliation":[]},{"family":"G&aacute;mez Nadia","sequence":"additional","affiliation":[]},{"family":"S&aacute;nchez Pablo","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Ambient Intelligence and Smart Environments","Ambient Intelligence Perspectives"],"original-title":[],"deposited":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T18:15:34Z","timestamp":1739988934000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=1875-4163&volume=1&spage=82"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-58603-946-2-82","relation":{},"ISSN":["1875-4163"],"issn-type":[{"value":"1875-4163","type":"print"}],"subject":[],"published":{"date-parts":[[2009]]}}}
