A Telemetry System Embedded in Clothes for Indoor Localization and Elderly Health Monitoring

  title={A Telemetry System Embedded in Clothes for Indoor Localization and Elderly Health Monitoring},
  author={Yoann Charlon and Nicolas Fourty and Eric Campo},
This paper presents a telemetry system used in a combined trilateration method for the precise indoor localization of the elderly who need health monitoring. The system is based on the association of two wireless technologies: ultrasonic and 802.15.4. The use of the 802.15.4 RF signal gives the reference starting time of the ultrasonic emission (time difference of arrival method). A time of flight measurement of the ultrasonic pulses provides the distances between the mobile node and three… CONTINUE READING
