Abstract
This article proposes an Internet of Things–based smart home system composed of a virtualized cloud server and a mobile phone app. The smart Internet of Things–based system includes a sensing network, which is developed with the ZigBee wireless communication protocol, a message queuing telemetry transport, a virtualized cloud server and a mobile phone app. A Raspberry Pi development board is used to receive packet information from the terminal sensors using ZigBee wireless communication. Then, the message queuing telemetry transport broker not only completes transmission of the message but also publishes it to the virtualized cloud server. The transmission can then be viewed through the website using a mobile phone. The designed app combines the application of the virtualized cloud server, client sensors and the database. Verification experiments revealed the measured average response time and throughput of approximately 4.0 s and 6069 requests per second, respectively, for the virtualized web server and approximately 0.144 s and 8866 packets per second, respectively, for the message queuing telemetry transport broker. The designed functions of the mobile phone app are a global positioning system home monitoring, family memo, medical care and near-field communication key. Both interlinkage and handler methods are proposed to facilitate a powerful function without delay in displaying information. The proposed system integrates with software and hardware to complete the data analysis and information management quickly and correctly. It can cater to user needs with superior ease and convenience.
Highlights
The Internet of Things (IoT) and Industry 4.0 have become global trends
We have proposed an IoT-based smart home system with a virtualized cloud server and a mobile phone app
The sensor-based intelligent networking system is composed of various sensors provided by a cooperative enterprise and used as the end devices, a ZigBee wireless sensing network, a gateway device with a Raspberry Pi single-chip computer and a virtualized web server local area network (LAN)
Summary
The Internet of Things (IoT) and Industry 4.0 have become global trends. Many terminal devices, such as handheld and wearable devices, can be connected to the Internet,[1] allowing communication among the devices as well as their access and control. IoT-based smart home system with a sensor, gateway, server, web browser and mobile phone app. MQTT is an ISO standard (ISO/IEC PRF 20922) publish/subscribe-based messaging protocol.[11] It works on top of the transmission control protocol (TCP)/Internet protocol (IP) and is a simple messaging protocol designed for high latency or unreliable networks.[12] It is popular for use in IoT and mobile applications consisting of premium bandwidth and battery power. The sensing datum of topic ( called message) is published to the MQTT broker The subscriber such as a web browser or mobile phone app subscribes to the Figure 3. If an emergency call is activated, the positioning information of the triggered mobile device is transmitted to the web server and the group members receive the message, which is displayed on their phone panels
