SartApproach to Dynamic Adaptivity Simulation in Fog Computing Scenarios

摘要

Fog Computing overcomes the problems of huge latencies in time-critical scenarios of data-intensive applications by leveraging the computation power of devices residing within the Edge instead of offloading all the data to the Cloud for processing. However, the complexity of computing at the Edge makes the resource planning and provisioning increasingly difficult for service providers, especially when it comes to the maintenance of a satisfactory-level Quality of Service (QoS). In this paper, a simulation approach to Fog Computing use cases involving the dynamic adaptivity mechanisms is presented. The simulation tool is implemented as an application run in web browser, relying on existing modeling tool and semantic-driven code generator.
