This work presents the Quality of Health Service (QhS), an IoT solution for a health patient monitoring environment and proposes an optimization mechanism with the Diffserv and EWS protocols. A mobile application is implemented for the specific healthcare team to have access to the system for viewing and modifying patient information. The analysis of vital signs in QhS solution took into consideration the network paradigm and IoT service, as well as the risk of the patient based on the EWS protocol. Thus, the QhS combines the Diffserv (network level) and EWS (application level) protocols for the optimization of data traffic in the system monitoring information and alerts. Additionally, It results in energy saving, still a vital resource in IoT devices.
