An increase in the number of notifications received, tends to reduce their tolerance . This article sets out a notification management system focused on user profiles and environments. The solution involves transferring notifications in a multi-device scenario using MQTT and CoAP technologies, while also adopting privacy criteria. It consists of three modules, the first of which was prototype and evaluated using real devices.engNotifications ManagementData PrivacyInternet of thingsconference object
