This special issue aims to draw together a number of papers which address challenges in the area of Edge or Fog computing. The inter-networking of physical devices, vehicles and buildings has led to the Internet of Things (IoT). But such cyber-physical systems need to respond in real-time and traditional Cloud computing does not support systems with such time dependency well. Time-sensitive applications are therefore moving from the centre to the edge of the cloud to avoid latency in communication. But when should a service sit on the edge of the cloud and when in the centre? How can applications be partitioned such that a time-critical part can be at the edge and time independent part in the Cloud? The decision might depend on the particular use at a particular time creating the desirability of migration and leading to a Fog of Things. Artificial intelligence or data-driven methods can be used to ascertain whether a service should sit on the edge or in the centre of the cloud and indeed whether, when and how migration should take place. Platforms and systems need to be developed to support such dynamics.
This special issue calls for papers from researchers working making inroads in this fascinating area so that we can gather together a state-of-the-art account. Research or review papers are sought. The following themes are of particular interest:
Implementing time-critical applications in a Cloud environment
Models of implementation for cyber-physical systems
Conditions and systems that support dynamic migration of applications
Trade-off between performance and energy efficiency among cloud and fog computing in complex and large applications
New network systems or architectures for dynamic environments in fog and cloud computing
New economic models for the configuration of cloud and fog environments
New standards for heterogeneous communication and network
New task and storage allocation models for cloud and fog computing
Interesting application stories and lessons
Service models for composing or integrating heterogeneous resources in cloud and fog
Security models for fog computing and the Internet of Things
