Lifecycle Based Modeling of Smart City Ecosystem

International audience ; Smart city services have an inevitable role in addressing the complexity of modern city operation. Smart transport, smart parking, smart energy, smart water and many others are examples of vertical smart city systems that are mainly concerned with its particular domain. Realizing the full promise of smart city will require interoperability among those systems and data fusion between heterogeneous components from different domains. In this regard, many standardization organizations have been working on modeling smart city and similar or related systems and concepts, such as Internet of Things (IoT) and Cyber Physical Systems (CPS), to ensure common technical grounding and architectural principles. Though, there is still a need to address the higher-level requirements of smart city as a complete ecosystem. To this end, this paper discusses different Smart City solutions and highlights lifecycle based modeling to better integrate people, processes, and systems; and assure information consistency, traceability, and long-term archiving.
