Fog computing or fog networking, also known as fogging, is an architecture that uses edge devices to carry out a substantial amount of computation, storage, and communication locally and routed over the internet backbone.
The role of geospatial in edge-fog-cloud computing - an ogc white paper the nist definition of fog computing[3] clarifies the distinction between edge.
Fog computing also is often erroneously called edge computing, but there are key differences.
Fog computing is the concept of a network infrastructure that stretches from the outer edges of where data is created to where it will eventually be stored, whether it be in the cloud or in a customer’s data center. Mung chiang, one of united states’ lead researchers on fog and edge computing gave quite a good definition of fog computing:.
Open fog consortium definition: “also referred to as mesh computing, it places applications, data and processing at the logical extremes of a network. Placing data and data-intensive applications at the edge reduces the iot volume and distance that data must be moved”.
National institute of standards and technology, (draft) the nist definition of fog computing (nist special publication 800-191) (aug. Managing the data generated by internet of things (iot) sensors is one of the biggest challenges faced when deploying an iot system. Traditional cloud-based iot systems are challenged by the large scale, heterogeneity, and high latency.
Nist defines mist computing as a lightweight and rudimentary form of fog computing that resides at the edge of the network fabric, bringing the fog computing layer closer to the smart end-devices.
Fog computing definition the term fog computing, originated by cisco, refers to an alternative to cloud computing. This approach seizes upon the dual problem of the proliferation of computing devices and the opportunity presented by the data those devices generate by locating certain resources and transactions at the edge of a network.

Edu abstract—internet of things (iot) was first explored in the 1980s, but even today there are many new concepts and technologies that are coming up in this field.
The adoption of cloud computing into the us government (usg) and its implementation depend upon a variety of technical and non-technical factors. A fundamental reference point, based on the nist definition of cloud computing, is needed to describe an overall framework that can be used government-wide.
An alternative to cloud computing is fog computing, a decentralized infrastructure in which data is accessed locally, which significantly reduces the amount of time it takes to access the data.
Companies, the meaning has been shifted that fog provides data, compute, storage, and application services to end-users, similar to cloud.
Beyond cloud computing: fog computing and mist computing the core issue of these problems lies in the centralized nature of a cloud computing architecture. After all, only the central nodes of the network have the capability to store and process data.
Fog computing is a term created by cisco that refers to extending cloud computing to the edge of an enterprise's network.

Jan 17, 2018 fog computing extends the concept of cloud computing to the network edge, making it ideal for internet of things (iot) and other applications.
Feb 13, 2020 in addition to the definition and characteristics of fog and edge computing, examples of practical implementation are presented.
Before explaining fog computing, we need to make sure we have a solid understanding of cloud computing, a concept that has become a common term in our lexicon. Cloud computing refers to access to “on-demand” computing resources, computing power, and data storage without the need for on-premise hardware or any active management by the user.
Apr 30, 2020 the term “fog computing” was first introduced by cisco, and it is defined as an architecture that extends the computational and storage capacity.

Ieee 1934 defines fog computing as “a system-level horizontal architecture that distributes resources and services of computing, storage, control and networking anywhere along the cloud-to-things continuum.
Fog computing is a platform for integrated compute, storage, and network services that is highly distributed and virtualized.
Cloud computing shifted the use of compute resources from asset-based physical resources to service-based virtual resources. Nist in its definition of cloud computing [2] describes a “measured service” as being one of the five essential characteristics of the cloud computing model.
