Real-time healthcare monitoring system using wireless sensor network

Abstract

This paper presents the design, implementation and evaluation of a wireless portable healthcare monitoring system. It has a set of medical sensors connected to an embedded microcontroller with a wireless communication module. By scanning the medical sensors, the embedded microcontroller checks if the patient health condition is normal or not. In the case of abnormal condition, the embedded unit transmits the measured signals directly to a medical centre through the internet. According to the patient health condition, a doctor will send medical advice to the patient to address the abnormality of the patient. A prototype system has been designed, implemented, and validated by both laboratory test and comparison with recommended medical standards. A detailed analysis and evaluation of the healthcare unit is given in the paper. The obtained results indicate that the proposed healthcare system is accurate in scanning, clear in monitoring, reliable in communication, and can be used as a portable medical kit for outdoor patient monitoring and supervising, or as a medical station at home.
