Abstract
The Internet of Things (IoT) has become a hot topic these years. It provides a key to information collection and sharing. In the application for healthcare, it is used to build applications such as remote monitoring and tele-care systems. Up to now, there have been various kinds of IoT applications for healthcare. Among all kinds of IoT applications for healthcare, the IoT-based Wearable Healthcare Monitoring System (WHMS) is one of the most popular applications. In this thesis, an IoT-based WHMS is designed by using the wide area network-sensor area network (WAN-SAN) architecture. In this system, there are three basic components: the master sensor node (MSN), the slave sensor node (SSN), and the central server. The SSN is responsible for measuring parameters from humans or environments. The MSN is responsible for discovering, connecting to SSNs, and collecting data from them. The central server is responsible for handling the connection between MSNs and SSNs, collecting data from all MSNs, and managing data. In theWAN-SAN architecture, we use Bluetooth and Wi-Fi, which are two of the most common communication technologies, to transfer data. There is also a website which provides visualized data and the GUI for the clients. People can observe data and configure the system on the website through the Internet. After implementation and evaluation, this system presents an adequate performance, with an average 0.713 seconds for data upload and 89.5 seconds for the system set-up. Besides, the MSN in this system is implemented on the Android platform, which means that people can use their Android mobile devices to set up MSNs everywhere. This system can be not only used in the controlled area such as the hospital environment, but also developed into a mobile-health application in the future.
