Abstract
Thanks to recent advances in artificial intelligence (AI), big data acquisition/processing techniques, and edge/cloud computing infrastructure, digital twins (DTs) are emerging and are triggering an imminent era of ubiquitous autonomy that is foreseen to transform businesses, industries, societies, and smart cities. DTs couple the cyber and physical realms through synchronous digital replicas for physical assets and their associated processes, which is foreseen to enhance monitoring, improve predictions, expedite optimization, and empower automation. However, supplying these DTs with accurate and timely data remains challenging, particularly in off-grid environments and emergency situations where network reliability and connectivity concerns are paramount. This talk explores a resilient and non-invasive data supply approach for DTs within smart cities, utilizing Space-Air-Ground Integrated Networks (SAGIN) in conjunction with Internet of Things (IoT) systems. By harnessing the wide coverage and flexibility of SAGIN, this approach enhances data availability and reliability across diverse landscapes, addressing potential disruptions from network failures or adverse conditions. Furthermore, the framework emphasizes non-invasive data collection strategies to optimize IoT device activation and participation, facilitating efficient DT construction and maintenance. The proposed SAGIN-IoT approach offers a scalable, and non-invasive data supply solution, positioning DTs as effective tools for resilience and sustainability in the face of evolving challenges in smart cities.
