A gateway based fog computing architecture for wireless sensors and actuator networks

The technologies of Internet of Things have been wide used in many areas such as intelligent building, logistics, security, and health. One of the key elements of the Internet of Things is Wireless Sensors and Actuators Networks(WSANs). Fog computing, the new concept of the cloud at the edge of the network, is considered the appropriate platform for many Internet of Things services and applications. In this paper we present a gateway based fog computing architecture for WSANs and argue that the key requirements of this architecture. This architecture mainly consists of master nodes and slave nodes, and manages virtual gateway functions, flows, and resources.
