Simulink Model of Wireless Sensor Network in Biomedical Application
Wireless sensor networks (WSN) comprises of many locally distributed sensor nodes in human body which monitor physical data such as body temperature, pressure, and heart rate. The use of sensor nodes for medical health has greatly attracted the attention of researchers recently because sensor nodes can be used to monitor patient's health condition or assist physicians in critical situations. This can greatly improve the existing patient care in health service. In this paper, Simulink model of health monitor using WSN has been designed. Parameters such as systolic blood pressure, heart rate, and body temperature have used to build the model and show the performance characteristics of various channels, i.e. AWGN, Rayleigh fading. The result shows that body temperature has the best performance in AWGN channel and heart rate has the best performance in Rayleigh fading channel.
