Computer Science Seminar: Towards Application-Aware Data Management at the Edge of the Network
- This event has passed.
Abstract: Edge computing confronts a massive data surge from edge-native applications like AR/VR, autonomous vehicles, and remote healthcare. The inherent limitations at the edge such as resource heterogeneity, network instability and inelasticity, make it difficult to deploy traditional cloud solutions to manage this data surge. The insight that application awareness is fundamental to handling resources for edge-native applications is the core of my research focus. Towards this, I have introduced four complementary data management techniques: (1) Cargo, a fault tolerant, SLO performance aware storage layer coupled with an edge computing framework (Armada) for heterogeneous edge environments; (2) A novel spatial-awareness based data placement and dynamic storage redundancy strategy for faster data delivery for edge-native applications; (3) ASTRA, a prefetching framework for mobile AR that leverages object associations, AR specific features, spatial/temporal relevance to achieve high cache hit rates; (4) Viveka, a context aware sensing framework for improving energy efficiency and reducing data generation on smart wearables while ensuring minimal impact on application accuracy. My immediate work will focus on extending the Viveka framework for remote health monitoring and exploring strategies to improve data imputation for data sensed from IoT devices. Looking towards the future, I plan to use the techniques identified in the current research to improve energy efficiency for autonomous vehicles, which can be considered a cluster of sensors.
