In the current cloud-based Internet-of-Things (IoT) model, smart devices (such as sensors, smart phones) exchange information through the Internet (routers and/or servers on cloud) to cooperate and provide services to users, which could be citizens, smart home systems, and industrial applications. Even though the cloud based IoT model describes a uniform, concise, and scalable solution for supporting IoT applications, the deployments of IoT applications on cloud and are facing the challenges originated from economic considerations, social concerns, technical limitations, and administrative issues. The Internet of Things expands its reach into virtually every domain, high-speed data processing, analytics and shorter response times are becoming more necessary than ever. Meeting these requirements is somewhat difficult through the current centralized, cloud-based model powering IoT systems, but can be made possible through fog computing brings computing resources and application services closer to the edge, the most rational and efficient spot in the range between the data source and the cloud. Keywords:- IoT, Fog Computing, Cloud 1. INTRODUCTION The Internet of Things (IoT) promises to make many items with consumer electronic devices, home appliances, medical devices, cameras, and all types of sensors part of the Internet environment [1].This opens the access to innovations that make possible new interactions among things and humans, and enables the realization of smart cities, infrastructures, and services that enhance the quality of life. The researchers approximation that the IoT could have an economic impact—including, for example, revenue generated and operational savings—of $11 trillion per year, which would represent about 11 percent of the world economy;[2] and that users will deploy 1 trillion IoT devices. The Internet of Things, can be a person with a heart monitor implant, a farm animal with a biochip transponder, an automobile that has fixed sensors to aware the driver when tire pressure is low or any other natural or man-made object that can be assigned an IP address and provided with the ability to transfer data over a network. IoT has evolved from the convergence of wireless technologies, micro- electromechanical systems (MEMS), micro services and the internet. The meeting has helped split down the silo walls between operational technologies (OT) and information technology, allowing unstructured machine-generated data to be analyzed for insights that will drive improvements. Fog computing extends the Cloud Computing model to the perimeter of the network, thus enabling a new type of applications and services. The characteristics of the Fog are: a) Low latency and location awareness b) Wide-spread geographical distribution c) Mobility d) Very huge number of nodes e) Prime role of wireless access, f) Strong presence of streaming and real time applications g) Heterogeneity. In this paper we argue that the above characteristics make the Fog the appropriate platform for a number of critical Internet of Things (IoT) services and applications, namely, Connected Vehicle, Smart Grid , Smart Cities, and, in general, Wireless Sensors and Actuators Networks (WSANs). 2. WHY IoT NEEDS FOG COMPUTING The Internet of Things (IoT) is one of the hottest mega-trends in technology and for good reason , IoT deals with all the components including Big Data Analytics, Cloud Computing and Mobile Computing . 2.1 The Challenge The IoT promises to bring the connectivity to an earthly level, every home, vehicle, and workplace with smart, Internet-connected devices. But as dependence on our newly connected devices increases along with the benefits and uses of a growing technology, the consistency of the gateways that make the IoT a functional reality must increase and make uptime a near guarantee [3]. As every appliance light, door, piece of clothing etc. The Internet of Things is poised to apply major stresses to the current internet and data center infrastructure. Gardner predicts that the IoT may include 26 billion connected units by 2020.
