Pervasive WSN based solutions applied to Health and Life-support systems

This paper describes a pervasive solution for Health and Life-support based LBS context-aware services, based on the integration and fusion of sensors and wireless technologies. It is proposed the integration of IEEE 802.15.4, RFID, Bluetooth, 3G and CAN devices and protocols to provide biotelemetry and alarm signals. The alarm signals and default communications links are context-aware to the physical environment. Since the system is location context-aware it will be analysed several indoor location solutions based on propagation models and a novel approach based on "proximity" paradigm and opportunistic networks is presented. A range of tests were carried out in an indoor environment and the results corroborate that the proposed system is viable, adaptable to different scenarios and compliant to the health care applications.
