This paper presents a patient monitoring system that can support multiple IoT (Internet of Things) rehabilitation devices. The physicians can plan the treatment for each patient via the Internet connection system with our software which has three sub processes: device configuration, monitoring, as well as feedback. The proposed system has been designed to support multiple devices and various types of rehabilitation devices by using the common HTTP protocol. This allows various IoT platforms to be programed to control various rehabilitation devices and connect to the Internet via WLAN, LAN, or cellular networks. The network connection test reported that the system can support many users’ devices sending the measurement data concurrently as well as correctly. Moreover, we propose a network selection algorithm for mobile devices that considers both Wi-Fi and cellular using energy efficiency, packet delay, and UDP success rate as key parameters to enhance network connection reliability. This algorithm is able to make sure that the network connection for transmitting the important data is always the very best in terms of reliability and efficiency. The system reliability test reported approximately 99% success rate for sending data to the servers with a low data rate. Consequently, this system works well in real world applications.
