INTEGRATION AND INTEROPERABILITY OF CONNECTED OBJECTS OF E-HEALTH OBJECTS IOT

Résumé

With the increasing surge of M-Health and smart city systems, the need to accommodate sensors and actuators, for an effective automation to take place, proves to constitute a critical requirement for Machine-to-Machine (M2M) communication to be maintained. The key elements for a successful M-Health system are power consumption and maintaining interoperability .It is in this context that the present work could be set, whereby a system dedicated to the elderly tacking and monitoring using their connected walking stick is implemented. Our system consists of a transmitter node positioned on the cane that transmits data related to the position and the state of the elderly, to a base station via LoRa technology, then the latter uses Message Queuing Telemetry Transport (MQTT) protocol to interact with the environment when a fall has occurred. Several experiments have been conducted to evaluate the area covered by our LoRa network and the power consumption of our system. The results indicate that the average covered area is around 6 km2 and the power consumption of our system is at least ten times lower than for a GPRS-based transmission system
