Navigating the Fog: A Comprehensive Survey and Comparative Analysis of Fog Computing Architectures

This research paper conducts an extensive examination and comparative analysis of various fog computing architectures. Delving into centralized, distributed, hierarchical, and specialized models, the study evaluates their impact on resource allocation, communication efficiency, and overall system responsiveness. Additionally, it explores emerging paradigms such as SDN-enabled fog, blockchain integration, and hybrid cloud-fog architectures. The findings provide valuable insights for practitioners and researchers, facilitating informed decisions in adopting and optimizing fog computing technologies across diverse applications and industries. Further, the main objective of the paper is to examine and compare various fog computing architectures based on parameters such as: resource allocation, latency, scalability, cost, and many others.
