This document discusses fog computing and its role in supporting Internet of Things applications. It defines fog computing as extending cloud computing to the edge of the network to enable applications requiring low latency, mobility support, and location awareness. Key characteristics of fog include its geographical distribution, support for real-time interactions, and role in streaming and sensor applications. The document argues fog is well-suited as a platform for connected vehicles, smart grids, smart cities, and wireless sensor networks due to its ability to meet latency and mobility requirements. It also describes the interplay between fog and cloud for data analytics, with fog handling real-time analytics near data sources and cloud providing long-term global analytics.
