**4.2 Large-scale sensor networks**

Fog computing has a very large-scale sensor network. These networks are connected between the fog nodes, clouds, and endpoint devices. Due to fog computing having a large-scale network since it is widely distributed, it can be used to monitor environments, smart city designs, smart agriculture implementations, and smart grid applications. These large-scale sensors send data continuously to the FN for processing, analysis, decision-making, and storage. These find applications in smart home devices, wearable devices, industrial sensors, connected appliances, smart healthcare devices, vehicles, environment monitoring devices, and smart agriculture devices.
