In this paper we describe an experimental evaluation, made in a real environment, of a solution that guarantees that there is no information loss when variable length hand-offs appear due to the movement of a node. Our proposal modifies the classical publish\/subscribe scheme by introducing an intermediate buffer that takes care of message transfer. Finally, we study the impact related to the connectivity of mobile devices of the use of the standard Linux<jats:italic>Network Manager<\/jats:italic>. We propose a cross-layer solution that improves the device connectivity in conjunction with the data layer management. We show that our solution improves the data delivery guaranteeing that no information is lost.<\/jats:p>","DOI":"10.1155\/2016\/4015625","type":"journal-article","created":{"date-parts":[[2016,8,15]],"date-time":"2016-08-15T17:01:38Z","timestamp":1471280498000},"page":"1-11","source":"Crossref","is-referenced-by-count":14,"title":["Improving MQTT Data Delivery in Mobile Scenarios: Results from a Realistic Testbed"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9040-5954","authenticated-orcid":true,"given":"Jorge E.","family":"Luzuriaga","sequence":"first","affiliation":[{"name":"Department of Computer Engineering, Universitat Polit\u00e8cnica de Val\u00e8ncia, Cam\u00ed de Vera, s\/n, 46022 Val\u00e8ncia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Perez","sequence":"additional","affiliation":[{"name":"Universitat Jaume I, Castell\u00f3 de la Plana, Avenida de Vicent Sos Baynat, s\/n, 12071 Castell\u00f3, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo","family":"Boronat","sequence":"additional","affiliation":[{"name":"Universitat Jaume I, Castell\u00f3 de la Plana, Avenida de Vicent Sos Baynat, s\/n, 12071 Castell\u00f3, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0038-0539","authenticated-orcid":true,"given":"Juan Carlos","family":"Cano","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Universitat Polit\u00e8cnica de Val\u00e8ncia, Cam\u00ed de Vera, s\/n, 46022 Val\u00e8ncia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5729-3041","authenticated-orcid":true,"given":"Carlos","family":"Calafate","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Universitat Polit\u00e8cnica de Val\u00e8ncia, Cam\u00ed de Vera, s\/n, 46022 Val\u00e8ncia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3753-0403","authenticated-orcid":true,"given":"Pietro","family":"Manzoni","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Universitat Polit\u00e8cnica de Val\u00e8ncia, Cam\u00ed de Vera, s\/n, 46022 Val\u00e8ncia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","year":"2014"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.adhoc.2012.09.006"},{"key":"3","year":"2016"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.compag.2008.01.005"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1145\/1993042.1993049"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/mwc.2007.358967"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1155\/2007\/56592"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/surv.2013.042313.00197"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-00491-4_1"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-38061-7_36"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/mnet.2013.6616110"},{"issue":"1","key":"16","doi-asserted-by":"crossref","first-page":"507","DOI":"10.1109\/COMST.2015.2388779","volume":"18","year":"2016","journal-title":"IEEE Communications Surveys & Tutorials"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/comst.2006.283821"},{"key":"23","series-title":"Lecture Notes in Computer Science","first-page":"250","volume-title":"Testing AMQP protocol on unstable and mobile networks","year":"2014"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1145\/1978802.1978811"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4015625.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4015625.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4015625.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,24]],"date-time":"2017-06-24T16:45:27Z","timestamp":1498322727000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/misy\/2016\/4015625\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":15,"alternative-id":["4015625","4015625"],"URL":"https:\/\/doi.org\/10.1155\/2016\/4015625","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"value":"1574-017X","type":"print"},{"value":"1875-905X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016]]}}}
