3. Healthcare IoT system architecture
Healthcare IoT systems are distinct in that they are built to
serve human beings, which inherently raises the requirements of
safety, security, and reliability. Moreover, they have to provide
real-time notifications and responses regarding the status of
patients. In a typical healthcare IoT system, to monitor patients’
activities and vital signs, the system has to ensure the safety of
patients. In addition, physicians, patients, and other caregivers
demand a dependable system in which the results are accurate
and timely, and the service is reliable and secure. To guarantee
these requirements, the smart components in the system require
a predictable latency and reliable communication with the
upper computing layer. The conventional cloud-based approaches
cannot assure the requirements of healthcare IoT systems, as the
connection to the cloud is less reliable and may incur additional
latency. In this article, we utilize a novel system architecture as a
suitable paradigm to address the aforementioned requirements.
