Resource Aware Placement of IoT Devices in Fog Computing

Fog computing is the new favorable technology that can support real-time cloud application services near to the physical IoT device at the network edge rather than the cloud. It is the decentralized internet-based computing and a layer between the cloud and IoT devices. For real time analytics and critical services, it must process the data as fast as possible. Fog computing can process and manipulate the data at the network edge devices in near real time. However, there is a resource limitation because the services are performed by the fog devices at network edge. So, it needs to utilize the resources of the fog devices. As a result, the placement of IoT (edge) devices on what fog devices is considered to get the efficient resource utilization of the fog devices in this paper. In order to get efficient resource utilization of the fog devices and reduce application delay, network usage and cost of execution in cloud, Fog Node Placement algorithm that finds the fog devices which is minimum distance and enough resource for the IoT (edge) devices is proposed. In addition, the effectiveness of the algorithm will be showed by comparing with traditional cloud placement and fog cloud placement with nearest distance.
