Model-Based Systems Engineering for Internet of Things (IOT) Based Mesh Radio Network

Abstract

Model-Based Systems Engineering (MBSE) has emerged as a paradigm shift in the development of complex systems, providing a holistic and integrated approach that transcends the limitations of conventional document-centric Systems Engineering (SE) methodologies. The literature identifies the traditional system development models like V-model, waterfall, and spiral models, document-centric models, leading to disintegrated development, increased costs, and project delays. This study focusses on employing ARCADIA, an integrated MBSE approach, to engineer an IoT-based mesh radio network system utilizing Software-Defined Radio (SDR) technology. ARCADIA a MBSE framework addresses the challenges of traditional document centric methods in system engineering. First phase, operational analysis, was conducted to capture and define stakeholder needs, operational environment, and conditions in which the system will operate. System analysis built upon operational analysis to formalize system requirements and articulate the dynamic behavior of the system. The third step involved defining the logical architecture, treating the system as a white box. The final step involved the development of the physical architecture, specifying how the system will be built, by defining system components, detailing interfaces, and conducting a final tradeoff analysis, ultimately leading to the final architecture of the system. ARCADIA implementation resulted in addressing the complexities of SDR system through enhanced communication, collaboration, and integrity of people, processes, and product. Its efficiency in requirement management, change management and seamless verification and validation resulted in efficient system development as per the user requirements. The cost benefit analysis identified the significant return on investment (ROI) of 10% on overall project costs. The impact of this research extends beyond the present, setting a path for future applications in various sectors like unmanned arial vehicle, aerospace, telecommunication, energy systems, smart cities, healthcare, and transportation. This study, implementation of MBSE for IoT based mesh radio network, opens doors for a transformative shift in approach to develop complex system across commercial and defense landscapes.
