Role of Fog Computing in IoT-Based Applications

Abstract

Internet of Things (IoT) as the name suggests is an interconnection of our daily usage items like smartphones, cars, laptops, tube lights, electric fans, etc. With the inception of IoT, each and every electronic item in this world would have an IP address. It would transform our way of interaction, making our life more autonomous. The essential requirement for the upcoming of this technology includes real-time response, low latency, fast processing and computation capabilities. These features being difficult to be handled by cloud data centres because of their remote location leads to development of a new technology called fog computing, which is an extension of cloud computing services from cloud data centres towards the edge devices. Fog computing possesses some security and privacy threats which are discussed in this paper. There is a need to resolve these threats so that people use fog-based IoT applications without any reluctance. Some of the solutions proposed are also mentioned in this paper.
