ABSTRACT
Medical systems can benefit from wireless sensor networks in a variety of applications. They can be used in disaster-response scenarios to allow for efficient tracking of patients and emergency response personnel, for continuous monitoring of patients in assisted living facilities, and for other mechanisms that require wearable sensors and provide efficient delivery of patient data. The use of sensors can enhance the care provided by a healthcare individual to a patient. The emergency response software infrastructure CodeBlue integrates wireless devices with a wide range of capabilities into a network that can be used for emergency care or disaster response. CodeBlue uses a radio frequency (RF)-based location tracking system called MoteTrack that operates using the low-power radio transceivers of the sensor nodes. Ko et al. propose the medical emergency detection in sensor networks (MEDiSN) which is also designed for monitoring patients in hospitals and disasters.
