Abstract
Fog computing spreads the cloud administrations and services to the edge of the system, and brings processing, communications and reserving, and storage capacity closer to edge gadgets and end-clients and, in the process, aims at enhancing versatility, low latency, transfer speed and safety and protection. This article takes an extensive and wide-ranging view of fog computing, covering several aspects. At the outset is the many-layered structural design of fog computing and its attributes. After that, chief advances like communication and inter-exchange, computing, etc. are delineated, while showing how these backup and facilitate the installations and various applications. Following that, it is shown that how, despite fog computing being a feature-rich platform, it is dogged by its susceptibility to several security, privacy, and safety concerns, which stem from the nature of its widely distributed and open architecture. Finally, some suggestions are advanced to address some of the safety challenges discussed so as to propel the further growth of fog computing.
Highlights
The internet has revolutionized the computers, communication and communication technology like nothing has ever before
Fog computing is able to offer an array of different Internet of Things (IoT) related services in the area of Internet of Vehicles - services such as feedback on conditions prevailing in urban areas and on streets, entertaining related data, traffic security etc., emanating from the linking and communication between vehicle to vehicle and vehicle to access doors [50]
Fog computing is not deemed as a substitution for cloud computing
Summary
The internet has revolutionized the computers, communication and communication technology like nothing has ever before. IoT implies an expansion of Internet through which physical objects are connected virtually, with the ability to provide smart services to its users This interaction between devices is slated to create gargantuan amounts and diversities of information and data. Fog computing serves to work as a connecting link between cloud and edge users This is accomplished by fog nodes by conjoining end appliances and devices and users through the use of wireless connection platforms like Wi-Fi, Bluetooth, 4G etc., to make available services such storage, computation and computing. This paper undertakes an extensive survey of fog computing It details various aspects of fog computing, including its design and architecture, main technologies involved, the applications where fog computing can be put to effective use and the security and trust issues and other challenges.
