Services and communications in fog computing

Abstract

In the current cloud-based Internet-of-Things (IoT) model, smart devices (such as sensors, smartphones) exchange information through the Internet to cooperate and provide services to users, which could be citizens, smart home systems, and industrial applications. As a result, Fog computing is a new paradigm that entitle cloud computing and services to meets the enhanced communications requirements of low latency, location awareness and mobility support. The Fog computing is located just one wireless hop away from associated end nodes, such as mobile devices, sensors and end users. Services are hosted at the edge of network, consequently, this reduces service latency, improves quality of service and provides a superior experience for end users. Hence, Fog computing paradigm offers ideal placement for low-latency offload infrastructure to support emerging applications that demand real-time or predictable latency, such as vehicle automation, augmented reality and wearable cognitive assistance.
