The PhD defence will be partially digital, in Kristen Nygaards sal (5370), Ole-Johan Dahls hus and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.

Ex auditorio questions: the chair of the defence will invite the attending audience at Kristen Nygaards sal to ask ex auditorio questions.

Main research findings

The central clouds have been the main infrastructure to process the current Internet of Things (IoT) data and provide IoT services. However, central clouds hardly fulfill the performance requirements of rapidly emerging intelligent applications, such as autonomous vehicles, and smart cities, all demanding high throughput, ultra-low latency, and high availability and reliability. Fog/Edge computing paradigms have been proposed to address the low latency and high throughput challenges by migrating cloud services to the proximity of local infrastructures and devices. Fog computing also brings many features different from cloud computing, such as location awareness, low latency, geographical distribution, and mobility. The requirements for fog programming are more dynamic and challenging than for cloud platforms, such as heterogeneity and dynamicity.

This thesis studies the fundamental issues of service orchestration and resource optimization in fog-cloud computing systems to improve the efficiency of dynamic fog/edge applications. The evaluations combine both testbeds and numerical simulations, and demonstrate the superior performance of the proposed frameworks, systems, and algorithms in the Edge-Fog-Cloud Continuum.
