New Concept of Healthcare Parameter Analysis on Sensor Node for Ubiquitous Healthcare System

This paper presents a new concept of healthcare parameter analysis on sensor node for ubiquitous healthcare system by detecting QRS-complex from real-time electrocardiogram (ECG). Wireless sensor nodes attached on the patient´s body and transmit ECG data continuously in ubiquitous healthcare system. So there are heavy communication traffics between sensor nodes and gateways. Our new developed platform for real-time analysis of ECG signals on sensor node can be used as an advanced diagnosis and alarming system for healthcare. Sensor node does not need to transmit ECG data all the time in wireless sensor network and to server PC via gateway. When sensor node detects suspicion or abnormality in ECG, then the ECG data in the network was transmitted to the server PC for further analysis and then can notify to the doctor´s personal digital assistant (PDA). This system can reduce data packet overload and save some power in wireless sensor network. It can also increase the server performance.
