Prototype Development of CAQSS Health Care System with MQTT protocol by using Atmega328

This paper gives information about the prototype development of Health Monitoring system which provides the analysis of Context awareness, Quality, Security and Smart- ness(CAQSS) for the various health parameters. Context inference in pervasive or extensive computing, associated with research challenges depicted health-care environments. Quality is a high-level representation of the state of the entity which captures operations, relationships, capabilities. Safe MQTT uses datagram transport layer security (DTLS) as a security protocol for communication and authentication of proposed experimental health devices to secure the transmission of confidential information. This paper shows the developments in IoT-based healthcare technology along with state-of-the-art device level, network level, application level architectures and platforms.
