Learn about Fog (also known as Edge) Computing
There’s new research Fog Computing Enabling Industrial Internet of Things: State-of-the-Art and Research Challenges that explains how doing computing near to where the sensing occurs allows for less data storage, less network bandwidth, real-time processing and ultra-low latency in detecting conditions. It reviews the methods, techniques, protocols used in fog computing and uncovers the challenges.
“Advanced IIoT applications will create a huge amount of data, causing a burden on the cloud. Even though cloud computing provides services to the edge devices, it incurs huge latency, resource allocation challenges, caching placement problems, energy consumption.”
The paper includes a deep analysis of Industry 4.0 and the applicability of fog computing. The key issues are bandwidth use, energy consumption, latency, throughput and resource usage.
