Abstract: During the past few years, Internet of things (IoT) has become an unprecedented buzzword in most areas of business and industry. It has also been one of the most revolutionary technologies in recent times, catalyzing a paradigm shift in traditional healthcare methods. This paper focuses on the monitoring and tracking of sleep health and designs a smart mattress system, which mainly includes information collection of mattress sensors, data transmission of communication networks, and distributed data management center of the message queuing telemetry transport (MQTT) protocol. Through the coordination of these parts, the sleep quality monitoring of a specific group of people can be achieved. The diagnosis of corresponding diseases, the tracking of health conditions, and the warning of special situations can be performed via the bed system.

Key words: Internet of Things, smart mattress system, medical diagnosis, MQTT protocol
