Towards Dynamically Reconfigurable IoT Camera Virtualization for Video Analytics Edge Cloud Services


Video analytics edge computing exploiting IoT cameras has gained high attention. Running such tasks on the network edge is very challenging since video and image processing are bandwidth-hungry and computationally intensive. IoT cameras are heavily dependent on environmental factors such as the brightness of the view. In this talk, I will share my experience on Octopus, an edge IoT camera virtualization and collaboration architecture that enables IoT cameras to accommodate multiple application operation semantics and dynamically adjust their configuration to preserve the required semantics in the presence of environment context changes. I will give details on its key techologies, an ontology-based application description model, a virtualization architecture with the container technology, and a context-aware dynamic reconfiguration scheme.
