Edge Computing: Classification, Applications, and Challenges

Edge computing is a relatively recent phenomenon in the computing world, which takes cloud computing services closer to the end user and is distinguished by fast processing and application response time, which leads to many advantages such as faster and more efficient data processing; Safety; reduced leakage on existing networks. Moreover, delay-sensitive applications may benefit from the Edge computing paradigm's low latency, agility, and location awareness. Significant research has been conducted in the field of Edge computing, which is reviewed in terms of recent technologies such as Mobile Edge Computing, Cloudlet, and Fog computing, allowing researchers to gain a better understanding of current and potential solutions. This article summarizes the edge computing paradigm classification, applications, and various challenges in detail.
