Mesh Network Based on MQTT Broker for Smart Home and IIoT Factory

Abstract

The Industrial Internet of Things (IIoT) provides connection among devices with the ability to monitor and exchange sensor data through the Internet. The need for reliability and high-quality data, as soon as possible that data monitoring able to afford the requirements from the IoT industrial standards. Recently, researchers have created more suitable communication protocols for IIoT devices, of which each has advantages such as XMPP, MQTT, AMQP in which MQTT is most widely used. This study proposes the utilization of MQTT as a communication protocol, which is one of the data communication protocols for IIoT. This work used temperature and humidity sensors, accelerometer sensors, current and voltage sensors because the digital and analog parameters are often needed as parameters of IIoT conditions. Data were scaled in real-time and stored in MySQL database. This study is also completed by mesh networks to deliver data from source to destination efficiently, these nodes using MQTT-based publish and subscribe. The result of this work demonstrates the transmission of data quality and reliability using MQTT protocol and the efficient power saving in mesh networks.

A Conceptual Curriculum Design Approach for Educating Engineers of and for the Future

“…The fourth industrial revolution is the current and developing environment in which disruptive technologies and trends. The current development is known as (i) The Internet of Things (IoT) (Luckyardi et al, 2022;Anh, 2022;Thapwiroch et al, 2021;Jebur, 2023;Pantjawati et al, 2020), (ii) Robotics (Castiblanco et al, 2021;Babalola & Omolafe, 2022a;Babalola & Omolafe, 2022b;Kamarudin et al, 2022;Zengin, 2022), (iii) Augmented reality (AR) (Ruhimat et al, 2023;Maulana & Kanai, 2022;Widiaty et al, 2021;Bangkerd & Sangsawang;Albar et al, 2021), professional practice. CDIO TM uses active learning and project-based learning techniques, using Conceive-Design-Implement-Operate as the contextual backbone for all of the classes.…”

A Systematic Review of the IoT in Smart University: Model and Contribution

“…The word "smart" is emblazoned on the phone to demonstrate its intelligence and to demonstrate how many activities or aspects of daily life it can help through various services offered (Nie, 2013). The term "smart" has expanded to encompass a wider range of topics than just a single item, such as "smart cities", "smart university", "smart grids", "smart home", "smart app", "smart harvesting", "smart material", "smart fashion", and so on Amin et al, 2022;Anh, 2022;Pechsiri & Puengsungwan, 2023;Castiblanco et al, 2021;Shaffiyah et al, 2022;Luckyardi et al, 2022;Chaihang & Puengsunwan, 2021). The meaning or definition of a smart university at this time has not been narrowed to a general understanding (Cocoli et al, 2014).…”

A systematic Literature Review of Internet of Things for Higher Education: Architecture and Implementation

“…The Internet of Things (IoT), commonly known as the Internet of Everything, is a network concept between software and machines in a global scope that aims to interact with each other. The main idea of IoT is to integrate the Internet, mobile devices, machines, electronic equipment, and others so that they are connected in real-time and can be shared by users (Talari et al, 2017;Saad, 2018;Thapwiroch et al, 2021;Anh, 2022;Pantjawati et al, 2020;). IoT connects people, devices, processes, and data that will enable stakeholders to find more efficient ways of turning data into valuable information (Shinrath et al, 2017;Mircea et al, 2021).…”
