ZigBee-based scheme for location information and data transmission

摘要

This paper proposes a ZigBee-based system and scheme to obtain location and vital health information. ZigBee systems are wireless communication systems defined by IEEE 802.15.4. Location information is obtained using a Link Quality Indication (LQI) function of the ZigBee system, which means the received signal strength. Vital health information is received as ZigBee sensor data when the terminal stations are moving. The proposed scheme facilitates the management of action history and health conditions for medical patients. Experiments using an actual ZigBee system confirm that the proposed scheme provides accurate location and vital health information using sensor data.
