A Bluetooth and Smartphone-Based Geofencing Solution For Monitoring Objects

Monitoring objects such as children, elderly, patients, visitors to ensure they do not move beyond a specified range such as a room, an area, a building or an isolation area is a common need. This monitoring is usually done manually by humans. This paper introduces a solution based on Bluetooth low energy technology combined with mobile technology to instantly detect the violation of a monitored object when he moves beyond the allowable radius from a given point. The solution is designed to be able to monitor thousands of objects living distributively at undefined areas with low cost, short time in deployment and without violating privacy of monitored people. This solution was proposed to support healthy center in monitoring certain COVID-19 contamination needed to be isolated in Vietnam.
