Network topology for the proposed Internet of Things (IoT) devices integrated with fog nodes and cloud. A brief overview of the components in the network topology: (1) IoT devices (blue circles) represent individual IoT devices in the network, each associated with a specific fog node. (2) Gateways (GT; orange hexagons) are used to connect the IoT devices to the fog nodes. (3) Fog nodes (FN; green triangles) are intermediate computing resources that process and store data from IoT devices. (4) A router (red square) connects the fog nodes to the private cloud and public cloud. (5) A private cloud (purple square) and a public cloud (yellow square) are the 2 cloud resources in the network.
