Fog and Edge Computing Issues and Challenges – A Review

Fog computing is the latest trend in the current scenario where sensors play a key role in managing and analyzing any device. With this huge spread of sensors and cloud comes various issues like security, network delay, resource utilization, and many more. In this work, we have tried to highlight these issues and existing proposed solutions to address these issues. In this architecture cloud is the main resource provider to compute the data so to address this issue resource allocation plays a significant role. Various nature-inspired algorithms and metaheuristic optimization algorithms are a few solutions to improve the performance of FOG and Cloud.
