Cost-Effective Time-Redundancy Based Optimal Task Allocation for the Edge-Hub-Cloud Systems

Abstract: Shifting tasks from the cloud to the edge Internet of Things (IoT) devices facilitates real-time decision support, yielding rise to the emerging edge-hub-cloud computing architecture. However, as edge devices tend to be more vulnerable to errors due to environmental/technological factors, the reliability of the application can be compromised due to this shift. We propose an optimization and design exploration framework for task allocation which maximizes reliability while respecting latency and energy constrai… Show more

“…Indeed, nodes may fail for several reasons, spanning from battery discharges or lack of connectivity to damages caused by the surrounding environment (e.g., bad weather conditions or accidental human activity). However, even if there is a large body of literature on Fog/Edge computing [ [2], very few approaches have considered the planimetryaware CPS design [3], [4] and the hardening of CPSs [5], [6]. Indeed, we claim that these two requirements have to be jointly considered and in a cost-effective way by instantiating and configuring a distributed computing platform with the minimal number of the cheapest edge nodes.…”

“…Existing redundancy techniques for soft error mitigation come with high cost on area, power, and performance, which edge devices cannot afford [6]. Consequently, it is important to explore the vulnerability of these devices at design time and apply selective redundancy at a fine-grained level, as needed [7]- [10]. Recent works that study the vulnerability in the presence of soft errors in various accelerators are reviewed in [4].…”
