Secure Data Collection And Transmission For Smart Health Monitoring System Using Iot Smart Devices

Abstract

The Internet of Things (IoT) is a concept that allows entities to detect and gather data from the real environment, then exchange that data via the Internet, where it may be analyzed and used for a variety of purposes. With the growing trend in the healthcare industry worldwide, it is preventive, predictive, personalized and participatory, and the reason for these trends is the increasing digitization of the healthcare industry. IoT in healthcare refers to a network of interconnected medical devices to collect patient health information and analyze data. In these settings, safe data collection and transfer to the centralized server are difficult to protect against various threats to gain unauthorized access to data. This paper proposes a safe and efficient method for collecting and transmitting healthcare data. It entails healthcare sensing devices and wearables communicating with one another to share confidential data with an aggregating node that can share data with the Fog server. An aggregator may be disconnected from the Fog server and unable to send data directly. However, it can share encrypted data with a neighbouring aggregator to transfer data to the Fog server by appending the encrypted data to its existing aggregated data. The Fog server can retrieve the measured value from the information and save them in a local repository, which can then be updated in the cloud later. The performance evaluation is presented compared to the other schemes regarding communication cost, transmission ratio and energy consumption.
