A Fog-based service enablement architecture for cross-domain IoT applications

Fog computing has emerged as a promising solution for Internet of Things. It enables services along the continuum from the edge to the cloud to reduce latency and mobile traffic, empowering end users in their vicinity. This article proposes a fog-based multi-level service enablement architecture for cross-domain IoT applications. It enables services sharing at network edges by a fog service overlay and introduces a hierarchical fog network for seamless service provisioning. This paper outlines the main features of this solution, and describes its architecture and some initial implementation results.
