Enabling Data Storage on Fog—An Attempt Towards IoT

Internet of Things (IoT) devices is generating large volume and variety of data. These unconnected devices are generating more than two exabyte of data each day. Today’s cloud models are not suited to manage these tremendous data. Moving them from these devices to the cloud for analysis would require huge bandwidth. Cloud servers communicate only through an Internet protocol (IP). But some of the IoT devices are machines that are connected to a controller using countless industrial protocols. Before sending the information retrieved from these devices to the cloud for analysis and storage, it must be translated to IP. The ideal place to analyze IoT data is near the devices that produce these data. This paper introduces fog computing or edge computing, a computational method that is suited for data generated by IoT devices and a few protocols to handle these data.
