In this paper, we propose a decentralized and distributed MANET-based (Mobile Ad-hoc NETwork) recommender system for open facilities. The system is based on mobile devices that collect sensor data about users locations to derive implicit ratings that are used for collaborative filtering recommendations. The mechanisms of deriving ratings and propagating them in a MANET network are discussed in detail. Finally, extensive experiments demonstrate the suitability of the approach in terms of different performance metrics. © 2021, The Author(s). info:eu-repo/grantAgreement/ES/AEI-FEDER/TIN2016-78011-C4-3-R info:eu-repo/grantAgreement/ES/AEI/PID2020-113037RB-I00 info:eu-repo/grantAgreement/ES/DGA/T64-20R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 5.019 2021 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE 46 / 146 = 0.315 2021 Q2 T1 1.211 2021 Artificial Intelligence 2021 Q2 7.8 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hermoso, Ramón Universidad de Zaragoza (orcid)0000-0002-1517-2820 5007 570 Universidad de Zaragoza Dpto.
