Hierarchical and Autonomous Fog Architecture, Shaik and Baskiyar, ICPP 2018.
Fog computing has been a topic around for several years. Since the cloud computing is a centralized infrastructure, it is usually deployed at a fixed place. Thus, cloud computing lacks the ability to deal latency-critical and bandwidth-intensive scenarios taking its inflexible deployment into account. As the 5G is approaching, IoT devices are expected to explode. Those devices will be more mobile than they are now, and delivering time-critical information will be problems. Some such information may be handled in an infrastructure nearby to meet the latency requirement, yet this kind of information may not be hard to dealt with due to its smaller size. Cloud machines will not necessarily get involved. Some nearby computing resources could be utilized. This brings the question: how to organize the resources?
