A Critical Review on the role of Fog Computing and Edge Computing in Internet of Things (IoT)

Abstract

Fog and edge computing are two of the most popular technologies that represent work in the succeeding domain areas: networking, privacy, security, and cloud computing in a comprehensive manner in the field of IoT. It is a growing and very important computing paradigm as compared to cloud computing where many services are available like computation, data storage, calculation, interpretation of data and networking offered which are implemented with the help of fog and edge layer at the edge network in multi-level, distributed manner and possibly in a support context. These cloud elements/roles are physically placed at network edges and virtualised at edge devices, feeling the “computing everywhere” concept. This study uses the most recent approach, which extends cloud computing to network edges and provides the technology and architectural era of both fog and edge computing platforms. In this paper, different computing paradigms have been discussed from the architectural and technological points of view which are as follows fog, edge computing mobile edge and cloud. To grasp the working of fog and edge computing comprehensive survey of mentioned domains areas has been discussed and surveyed from the technological and architectural point of view. In this paper, current architectures are referencing and describing core areas of fog and edge computing in a comprehensive manner. Architectures are presented on the following areas of IoT i.e., networking, security, software, security and applications are evaluated based on the proposed model.
