[8][9][10][11][12][13], Fog networking supports the Internet of Things (IoT) concept, in which most of the devices used by humans on a daily basis will be connected to each other. The terminal layer is the basic layer in fog architecture, this layer includes devices like mobile phones, sensors, smart vehicles, readers, smartcards, etc. this is often often done to enhance efficiency, though it’s going to even … Privacy in the case of fog computing data can include use-based privacy, data-based privacy, and location-based privacy. Data is removed from the temporary layer once data is moved to the cloud, from this layer. [32], IEEE adopted the Fog Computing standards proposed by OpenFog Consortium.[33]. Many of these devices will generate voluminous raw data (e.g., from sensors), and rather than forward all this data to cloud-based servers to be processed, the idea behind fog computing is to do as much processing as possible using computing units co-located with the data-generating devices, so that processed rather than raw data is forwarded, and bandwidth requirements are reduced. This layer has high storage and powerful computing capabilities. Fog node distribution (physical as well as geographical, along with the topology and protocols used form key architectural features of a fog architecture.

Fog nodes ensure services to the end devices. Fog networking consists of a control plane and a data plane. We’ve already got used to the technical term cloud, which is a network of multiple devices, computers and servers connected to each other over the Internet. The performance of applications as well as their present state is also monitored. The advantages of fog computing architecture include reduced latency, improved security, greater reliability, and the ability to provide location awareness. An edge can be a hop distance from the end device. The protocols used at different layers, the particular devices that are used at different layers and their functionalities, specifications are identified by going through the fog architecture. Fog computing is more energy-efficient than cloud computing. Data is cleaned and checked for any unwanted data present. The frontend — consists of client devices (computers, tablets, mobile phones). Data impurity is removed and only useful data is collected. In contrast to the cloud, fog platforms have been described as dense computational architectures at the network’s edge. The backend — consists of data storage and processing systems (servers) that can be located far a… This layer is involved with the privacy of data, the integrity of data. It allows for low latency as the network carries less traffic. Th… Fog computing distributes the cloud resources throughout the network by introducing fog devices with limited resources between cloud and edge devices [21,22].

Zhu, and S. Addepalli, "Fog computing and its role in the internet of things," in Proceedings of the First Edition of the MCC Workshop on Mobile Cloud Computing, ser. The scope of fog computing starts from the outer edges where the data is collected to where it will be stored eventually. Fog computing has a distributed architecture to reduce the load on the cloud. Fog computing refers to decentralizing a computing infrastructure by extending the cloud through the placement of nodes strategically between the cloud and edge devices. Fog is an emerging, distributed architecture that bridges the continuum between cloud and connected devices that doesn’t require persistent cloud connectivity in the field and factory. [20], In 2011, the need to extend cloud computing with fog computing emerged, in order to cope with huge number of IoT devices and big data volumes for real-time low-latency applications. Fog computing is a decentralized computing infrastructure in which data, compute, storage and applications are located somewhere between the data source and the cloud.

Figure 4.3 presents a reference architecture for fog computing. © 2020 - EDUCBA. Fog computing (FC) and Internet of Everything (IoE) are two emerging technological paradigms that, to date, have been considered standing-alone. In a fog computing architecture, each link in the communication chain is a potential point of failure. Like edge computing, fog computing brings the advantages and power of the cloud closer to where data is created and acted upon. In this paper, we propose to develop a Vehicular Fog Computing (VFC) architecture to implement cooperative sensing among multiple adjacent vehicles driving in the form of a platoon. The Fog nodes are situated in-between end devices and cloud data centers.
