Cloud Centric Conceptual Architecture And Simulation For The Interconnection Of Selected Ethiopia’s Mega Projects Via Internet Of Things

Abstract

This thesis presents the results of the assessment of CloudIoT architecture for selected Ethiopia’s mega-projects. Appropriate solutions were proposed based on the requirements collected from the literature review. In addition, the proposed interconnection architecture was supported via solid simulation environment based an architectural model. An explanatory and qualitative method of research was used for this thesis work. The defined problems were investigated qualitatively based on availability, flexibility and manageability metrics. In addition, an object oriented analysis method was used to structure the requirements of the architectural design and simulation formulation. The necessary data of research were mainly derived from documentation analysis about the current-state-of-the–art CloudIoT technologies. Primarily, Gaps were identified from existing CloudIoT architectures that were assumed to go with the mega-projects perspective. The proposed architectural contribution of this thesis work is two-fold. The first is the interconnection architecture and the second is data-centered architecture. Both architectures were proposed based on four common elements which are: the IoT devices, the intelligent gateway, the fog edge cloud and the core cloud. Furthermore, modeling and simulation was done taking the model as a prototype. To qualitatively assess the architectures, an appropriate validation metrics (availability, flexibility and manageability) were prepared based on architectural requirements. Besides, intensive validation and evaluation of the interconnection architectures are presented in this thesis work. Investigations made via the modeling and simulation under this thesis work have shown that interconnection of multiple mega projects is possible through the means of CloudIoT. In summary, conclusions and recommendations were proposed based on the evidences of the modeling and the simulation. The thesis result encourages the Ethiopian government to craft a new GTP plan that should interconnect the mega projects using cloud computing and internet of things. The CloudIoT research communities should use the CloudIoT for interconnecting multiple mega-projects rather than focusing on single mega-project. Finally, the Contiki Cooja developers should add multiple accessibility options to access the external environment from the Cooja simulator.
