Analyzing Effects of Resource Distribution on Performance of Fog Infrastructure

As the number of Internet of Things (IoT) devices are increasing, the data that is being produced is increasing as well. Cloud computing provides services for data storage and processing by using IT infrastructure on remote locations. With the increase in data, the load on cloud computing and communication infrastructure is on the rise as well, leading to increase in response time and latency. Fog computing addresses this issue to an extent by brining processing closer to the edge. As fog infrastructures are significantly different from cloud in terms of scale, processing capacity, bandwidth etc., they require focused analysis to improve their performance. In this paper, we analyze impact of resource distribution in small-scale fog infrastructure on its performance and resource utilization. We examine different topological arrangements of fog devices with varying resources. Our results show that the topological arrangement of fog resources affects the overall performance of fog infrastructure.
