Researchers from the University of Technology Sydney have developed a new framework to enhance the capabilities of Unmanned Surface Vehicles (USVs). The team, led by Thien Tran and including Quang Nguyen, Jonathan Kua, Minh Tran, Toan Luu, Thuong Hoang, and Jiong Jin, has proposed a distributed Cloud-Edge-IoT architecture to overcome the limitations of current maritime Industrial Cyber-Physical Systems (ICPS).
The researchers identified that onboard computational constraints and communication latency significantly restrict real-time data processing, analysis, and predictive modeling in USVs. These limitations hinder the scalability and responsiveness of maritime ICPS, which are crucial for the advancement of maritime autonomy. To address these challenges, the team leveraged design principles from the Cloud-Fog Automation paradigm to create a hierarchical architecture.
The proposed architecture comprises three layers: a Cloud Layer, an Edge Layer, and an IoT Layer. The Cloud Layer is responsible for centralized and decentralized data aggregation, advanced analytics, and future model refinement. This layer handles complex computations and long-term data storage, providing a robust backbone for the system. The Edge Layer executes localized AI-driven processing and decision-making, enabling real-time responses to dynamic maritime environments. This layer reduces latency by processing data closer to where it is collected. The IoT Layer is tasked with low-latency sensor data acquisition, ensuring that data from various sensors is quickly and efficiently gathered for immediate use.
The researchers conducted experimental tests to evaluate the performance of their proposed architecture. The results demonstrated significant improvements in computational efficiency, responsiveness, and scalability compared to conventional approaches. The team achieved a classification accuracy of 86% and observed enhanced latency performance. These improvements highlight the potential of the Cloud-Fog Automation paradigm in addressing the low-latency processing constraints and scalability challenges in maritime ICPS applications.
The practical applications of this research are substantial. By adopting the proposed Cloud-Edge-IoT architecture, USVs can achieve more robust autonomy and AI-driven decision-making. This advancement is crucial for the future of maritime operations, where unmanned vehicles play an increasingly vital role. The modular and scalable framework offers a practical solution to enhance the capabilities of USVs, making them more efficient and reliable in various maritime environments.
This research not only advances the field of maritime autonomy but also sets a precedent for the integration of Cloud-Fog Automation in other industrial cyber-physical systems. The findings provide a blueprint for developing more responsive and scalable systems, paving the way for future innovations in autonomous technologies. Read the original research paper here.
