A Low-Costed Positioning System Based on Wearable Devices for Elders and Children in a Local Area

Abstract

Internet of Thing (IoT) technology is an attractive issue because it has been applied widely to a number of aspects, such as smart home, indoor positioning, and autonomous produce and control. Currently, the cares of elders and children existed some problems of management for several years. Therefore, the IoT is expanded to position and monitor walks of elders and children in a local area. However, the proposed positioning or monitoring systems have high costs and power consumption. In addition, most proposed systems are demanded to match up a smartphone, but the smartphones bring other problems for elders and children. Therefore, a wearable device positioning system, in this study, is proposed. This study main aims at addressing the challenges for those proposed systems to develop a low cost and power consumption system by wearable devices and raspberry pi boards through Bluetooth low energy (BLE) transmission. Furthermore, the text marquee and Google Cloud Message push-notification are added to the wearable device positioning system to prevent dangers occurred in the bathrooms and outdoor areas.
