The Resilient Edge: Evaluating Graph-based Metrics for Decentralised Service Delivery

Abstract

Providing resilience, the notion of persistence service delivery in the face of challenges to operation, is seen as increasingly vital with the continued evolution of service-delivery paradigms such as Fog and Edge operating in hostile and uncertain environments. Additionally, to achieve resilience in these environments, a number of unconventional system and network architectures have been produced, which also require novel methods of resilience evaluation. Using a novel bio-inspired embryonic fog service delivery platform, we evaluate a number of graph resilience metrics and propose a new method using assortativity to evaluate the state of service fluctuations over time.
