Abstract: 

 In order to overcome the scalability problem of the traditional Internet of Things (IoT) architecture (i.e., data streams generated from distributed IoT devices are transmitted to the remote cloud via the Internet for further analysis), mobile edge computing (MEC) has been proposed to provision IoT by handling the data streams at the mobile edge. Specifically, each base station is connected to a fog node, which provides computing resources locally. On top of the fog nodes, the software defined networking (SDN) based cellular core is designed to facilitate packet forwarding among the fog nodes. Meanwhile, we propose a hierarchical fog computing architecture in each fog node to provide flexible IoT services: each user’s IoT devices are associated with a proxy VM (located in a fog node), which collects, classifies, and analyzes the devices’ raw data streams, converts them into metadata, and transmits the metadata to the corresponding application VMs (which are owned by IoT service providers). Each application VM receives the corresponding metadata from different proxy VMs and provides its service to users. In addition, a novel proxy VM migration scheme is proposed to minimize the traffic in the SDN-based core.
