Fog Computing and Its Role in Development of Smart Applications
Mandeep Kaur Saroa, Rajni Aron · 2018
In 21st century, Internet of Things (IoT) is playing an important role in developing Smart cities. With the growth of IoT, data is growing with acceleration. As the data is growing the need to store data is also increasing. More the data, the latency will be high to store and retrieve data from the cloud. The concept of fog computing was originated to diminish the latency for accessing the data to and from the cloud. Fog computing imparts the storage, computing as well as networking services at the end point of the network. Fog nodes also have limited computational capabilities. Due to some weaknesses, fog computing and cloud computing cannot sustain alone, so both these technologies are integrated to build smart IoT infrastructure for Smart city. Fog computing have a major role and supreme responsibility in development of a Smart city. This paper discusses various applications of fog computing and their implementations in a Smart cities. It also proposes a prototype for Waste management system in a city. Fog computing can help to govern the waste collection of the city in a smart way. On the basis of our review, several open concerns and challenges of fog computing are discussed, and the directions for future researchers have also been discussed.
