Dynamic Hardware Redundancy Approaches Towards Improving Service Availability in Fog Computing

The distributed nature of fog computing is designed to alleviate bottleneck traffic congestion which happens when a massive number devices try connect more powerful resources simultaneously. Fog focuses on bringing data processing geographically closer source utilizing existing such as routers and switches. This heterogeneity an important feature challenge at the same time. To enhance availability with nature, several studies have been conducted using different methods placement policies scheduling algorithms. paper proposes model that includes extra layer duplex management system. designated for operating managers warm spares ensure higher disseminated paradigm. A Markov chain utilized calculate probabilities each possible state in proposed along analysis. By standby system, we were able increase 93%.
