Abstract

Internet of Things (IoT) devices are more and more used in our today's life. However, as the amount of connected devices increases, the communications between them are more and more difficult to scale. The MQTT communication protocol has come to solve this issue. The MQTT protocol is a communication protocol between IoT devices that aims to centralise the communications inside one broker. However, a typical MQTT communication involves hundreds of messages per minute. This is then hard to analyse an MQTT communication with packet sniffer tools like Wireshark. The goal of this master thesis is to provide an appropriate and publicly available tool to visualise and analyse MQTT communications for debugging purposes. This report reviews the goals of this project: create several MQTT broker environments on the same system, display the set of published messages, the state of a broker, filter the published messages, and display telemetry on the number of published messages. This thesis report then goes through the MQTT protocol and its various types of packets. The high-level architecture is discussed with the first decisions for the role of each component that will be developed: a broker to record the MQTT data and a viewer to visualise it. We then decide on the type of database to store the recorded data persistently, the kind of data to record which is interesting to display to the user, and how this data should be stored. The architecture of the broker is reviewed as well as the technique used to manage the several independent MQTT broker environments. With this, we discuss how to save the events that happen in an MQTT broker and the techniques used to scale the project with a big amount of MQTT messages. To conclude the discussion about the architecture, we discuss the plugin system that allows extending the viewer, how the MQTT data should be stored and represented in the viewer, and how the user should have access to the required features. We then review how complex filters can be built into the viewer. We then discuss the development methodology of this project. The implementation details are then reviewed with the different technologies used in this project. We will talk about the difficulties encountered during the deployment and explanations on how to deploy this project easily. The results of this project are finally reviewed with the latencies encountered when the broker faces a lot of traffic and some screenshots of the viewer. A discussion is made about the further possible improvements on this project. Additional documents and documentation are provided at the end of this report.

Abstract

In past decades, various sensor technologies have been used in all areas of our lives, thus improving our quality of life. In particular, imaging sensors have been widely applied in the development of various imaging approaches such as optical imaging, ultrasound imaging, X-ray imaging, and nuclear imaging, and contributed to achieve high sensitivity, miniaturization, and real-time imaging. These advanced image sensing technologies play an important role not only in the medical field but also in the industrial field. This Special Issue covers broad topics on imaging sensors and applications. The scope range of imaging sensors can be extended to novel imaging sensors and diverse imaging systems, including hardware and software advancements. Additionally, biomedical and nondestructive sensing applications are welcome.

Abstract

Advanced intelligent (ADI) control through Versatile Intelligent Portable (VIP) Platforms is a rapidly developing, complex, challenging field with great practical importance and potential. ADI control is an interdisciplinary field which combines and extends theories and methods from control theory, computer science, and operations research areas with the aim of developing controllers that are highly adaptable to significant unanticipated changes. Deep research and communicating new trends in the design, control, and applications of the real time control of intelligent sensors systems using advanced intelligent control methods and techniques is the main purpose of this book. Innovative multi-sensor fusion techniques, integrated through VIP platforms, are developed and combined with computer vision, virtual and augmented reality (VR&AR), and intelligent communication, including remote control, adaptive sensor networks, human–robot (H2R) interaction systems, and machine-to-machine (M2M) interfaces. Intelligent decision support systems (IDSS), including remote sensing, and their integration with DSS, GA-based DSS, fuzzy sets DSS, rough set-based DSS, intelligent agent-assisted DSS, process mining integration into decision support, adaptive DSS, computer vision-based DSS, and sensory and robotic DSS are highlighted in the field of advanced intelligent control. Approaching new technologies using advanced intelligent control through versatile intelligent portable platforms involves complex multidisciplinary research covering enhanced IoT technologies and applications in the 5G densification era, bio-inspired techniques in future manufacturing enterprise control, cyberphysical systems approach to cognitive enterprise, developing the IT Industry 4.0 concept, industrial systems in the digital age, cloud computing, robotics, and automation with applications such as human aid mechatronics moving in unstructured and uneven environments, rescue robots, firefighting robots, rehabilitation robots, robot-assisted surgery, and domestic robots.
