An IoT approach to an ECG online monitor system in an android application

Abstract

We currently live in a world with many paradigms and being subject to changes such as the ones related to mHealth. With the advances in Mobile Cloud Computing (MCC), new concepts have been introduced, such as the Internet of Things (IoT) and the use of bluetooth for low power data transmission. On the other hand, sensors like the ones used in mHealth can monitor vital signals and send them over the internet for many different purposes. This paper shows an approach of MCC and Internet of Things (IoT) applied to mHealth, which suggests a new architecture developed to an application for mobile devices that can receive electrocardiographic signals from a 3-lead ECG sensor, using cloud data storage and a dedicated frame architecture between the ECG sensor and the mobile device that allows error correction. The proposed approach focuses on an mHealth scenario, where a secure connection algorithm between the bluetooth module and the local android device must be established, so that the system as a whole knows if there is too much error within the local communication, or if the signal is up to be sent to the cloud.
