Fog Computing Applications in Smart Cities: A Systematic Survey

Nowadays, the smart city is a topic that has attracted the attention of many researchers, engineers and even the public because of to its pervasive and vast effect on everyday life. The technologies used to realize the smart cities are often based on cloud computing. As a result, they have carried the limitations of cloud computing, such as unreliable latency, lack of mobility support, and location awareness. Fog computing provides different solutions to these problems. Although efforts have been done in the area of fog computing applications in smart cities, it is still difficult to find a systematic reliable survey that covers this area. This article aims to provide a comprehensive overview based on a systematic literature review of current works that have been done in the area of fog computing applications in smart cities. In addition, a different analytical comparison of related works, the trends, and future research directions are pointed out in this article.
