Let there be four fog nodes F1, F2, F3, F4, connected with several IoT devices. The data generated from the IoT devices can be processed either in single or multiple fog nodes. The Fog node can accommodate up to 20 GB, 90 GB, 28 GB, and 46 GB respectively. Further these Fog nodes F1, F2, F3, F4 take 12µs, 18 μs, 28 us, and 22 us to complete 10 GB task. A cloud architecture is also available to execute different tasks, it can process 20 GB of task in 8 us. An IoT device requires 246 GB of data. The time taken to transmit data packets to the cloud is longer than the time taken to transmit data packets to fog nodes. However, device is associated with a critical application. Assume that the device can split the data into multiple segments and segments can be assigned among the fog nodes and the cloud for processing. For the given scenario, compute the total time required to process 246 GB of data.
