IEEE Access Special Section Editorial: Sustainable Infrastructures, Protocols, and Research Challenges for FOG Computing

Cloud computing continues to provide services related to storage and computation by managing a pool of resources that usually costs more financially as well as in terms of latency. On the other hand, due to the distribution of applications and services closer to the end-users, academics and industry experts are now advocating for going from large, centralized cloud computing infrastructures to a range of computing nodes located at the edge of the network. Principally, fog computing extends the services and resources of the cloud closer to users, which facilitates the leveraging of available services and resources in the edge networks. Fog computing is an attractive solution to delay- and resource-constrained large-scale wireless and real-time applications, with its features such as low latency, location awareness, and its capacity to process large numbers of nodes with wireless access.
