Hybrid Network Protocol Information Collection and Dissemination in IoT Healthcare

In recent years, the internet of things (IoT) has grown in significance, affecting a larger variety of areas of daily life in a wider number of nations. As a result, there has to be a trustworthy system for collecting and disseminating data sent online by trillions of sensors to trillions of actuators. Only a few healthcare scenarios necessitate the transmission of data in real time; in most cases, monitoring relies on the average of sensor readings. Real-time transmission is seldom ever necessary in healthcare applications. Constrained Application Protocol (CoAP) and Message Queuing Telemetry Transport (MQTT) are the two most popular application layer protocols utilized by low-resource devices and Internet of Things applications. However, this study created an architecture that combines MQTT’s quick availability with CoAP’s dependable and fundamental communication to increase healthcare’s reliability and efficiency. Whether the control server uses MQTT or CoAP for message exchange depends on how important the object being controlled is. MQTT protocol proposes several advantages over CoAP such as reliability, real time transmission, broadcasting to topics’ subscribers etc. The combination of both MQTT and CoAP allows to filter the health data into two categories, severe symptoms measurements of emergency are published and diffused via brokers using MQTT while normal measurements are conveyed to normal servers using CoAP.
