Abstract
Internet of Things is the future of the Internet. It encircles a wide scope. There are currently billions of devices connected to the Internet and this trend is expecting to grow exponentially. Cisco predicts there are at present 20 billion connected devices. These devices, along with their varied data types, transmission rates and communication protocols connect to the Internet seamlessly. The futuristic implementation of Internet of Things across various scenarios demands the real time performance delivery. These range from RFID connected devices to huge data centers. Until date, there is no single communication protocol available for envisioning IoT. There is still no common, agreed upon architecture. Hence, huge challenges lie ahead. One of the ways to envision Internet of Things is to make use of Fog Networks. Fog is essentially a cloudlet, located nearer to the ground. It offers lower latency and better bandwidth conservation. The Fog or Fog computing is a recent concept. The OpenFog Consortium is a joint effort of many vendors. Its latest work is the background study for realizing Fog as a possible paltform for activating Internet of Things. This paper revolves around Envisioning Internet of Things using Fog computing. It begins with a detailed background study of Internet of Things and Fog Architecture. It covers applications and scenarios where such knowledge is highly applicable. The paper concludes by proposing Fog Computing as a possible platform for Internet of Things.
Highlights
Internet of Things (IoT) is the future of the Internet
The various Things, or devices that are connected to the IoT are heterogeneous in nature
They range in size, data type and communication speed
Summary
Internet of Things (IoT) is the future of the Internet It enables inter connectivity among devices and platforms. A popular approach is to assign each device, anIPv6 address This enables the devices to be identified exclusively. On a more advanced level, Uniform Resource Identifiers (URI) can be deployed These include both IPv6 addresses and Uniform Resource Locators (URLs). The “Pay-As-You-Go” model is an efficient way of managing data centers, for processing client applications and batch processing This shift in the paradigm towards centralized cloud computing is primarily due to the ease in management. Uninterrupted Internet connection might be an expensive requirement for many small systems They could be embedded devices, pervasive systems or simple battery operated circuits [2]
