Outdoor wireless healthcare monitoring system for hospital patients based on ZigBee

Advances in embedded computing systems have resulted in the emergence of Wireless Sensor Networks (WSNs), which provide unique opportunities for sensing physical environment of our daily lives. ZigBee-compliant WSN platforms have been proposed for Healthcare monitoring, smart home, industrial monitoring and sensor, and other applications. In this paper, we using TI CC2430 and CC2431 chipsets with Z-Stack designed an outdoor patients' healthcare monitoring system, for tracking patients, and helping doctors and nurses to keep tabs on their patients' health remotely. Furthermore, several important techniques are elaborated, including reliable communication, localization algorithm and backup power, which can enhance the system performance. Finally, presented some suggestions for future development are presented by us.
