Design and Implementation of Low-Cost Fog Computing Architecture for IoT-Based Applications

Internet of Things (IoT), currently cloud IoT infrastructure is shifting toward fog computing through the task offloading process. Fog computing provides computing capabilities that bring closer to the IoT devices. By task offloading shifting to the fog, nodes can avoid high network congestion. Fog computing can improve the quality of service, especially for delay-sensitive applications by enabling low latency requirements. In the IoT infrastructure, low-cost devices are used for less expensive infrastructure deployments. Raspberry pi is used for computing infrastructure with cheaper development. A small single-board computer not only has high computing capacity but also allows high portability.
