Fog or fog computing, also known as fog, is an architecture that uses one or more collaborative end-user clients or near edge devices to perform a substantial amount of storage (rather than being stored primarily in data centers cloud, rather than routing through the Internet backbone), control, configuration, measurement and management (rather than controlled primarily by network gateways such as the LTE main network).
Fog computing can be perceived both in large cloud systems and in large data structures, referring to the increasing difficulties in accessing information objectively. This results in a lack of quality of the content obtained. The effects of cloud computing on cloud computing and large data systems may vary; However, a common aspect that can be extracted is a limitation in the precise distribution of content, an issue that has been addressed with the creation of metrics that try to improve accuracy.
The fog connection consists of a control plane and a data plane. For example, in the data plane, cloud computing allows computer services to reside on the edge of the network, as opposed to servers in a data center. Compared to cloud computing, cloud computing emphasizes proximity to end users and customer goals, dense geographic distribution and pooling of local resources, reduced latency and savings in column bandwidth to achieve a better quality of service (QoS) user experience and redundancy in case of failure.
The fog network supports the Internet of Things (IoT) concept, in which most devices used by humans on a daily basis will be connected to each other. Examples include telephones, health monitoring devices that can be used, vehicle connected and augmented reality using devices such as Google Glass.
SPAWAR, a division of the United States Navy, is designing and testing a scalable and secure Disruptive Tolerant Mesh Network to protect strategic military assets, both stationary and mobile. Machine control applications, which run on the mesh nodes, "take control", when Internet connectivity is lost. Use cases include the Internet of Things, p. smart drone swarms.
ISO / IEC 20248 provides a method by which data of the objects identified by edge computation using an Automated Identification Data Collector (AIDC), a bar code and / or an RFID tag, can be read, interpreted , checked and made available in the "Fog" the "edge" even when the AIDC tag has moved on.
