Computational Perspective of the Fog Node
share
Fog computing is a recent computational paradigm that was proposed to solve some weaknesses in cloud-based systems. For this reason, this technology has been extensively studied by several technology areas. It is still in a maturing stage, so there is no consensus in academia about its concepts and definitions, and each area adopts the ones that are convenient for each use case. This article proposes a definition and a classification relying on a computational perspective for the fog node, which is a fundamental element in a fog computing environment. In addition, the main challenges related to the fog node are also presented.
