Fog Computing in 5G Mobile Networks: A Review

Abstract

The existing Internet infrastructure cannot meet the demands of the exponential growth in data users need to access. Therefore, Fog Computing (FC), Internet of Things (IoT), and 5G are upgrading conventional data transfer with innovative solutions and intelligently processing data to improve performance. Fog computing is considered a central component in the growth of the new 5G networks and the Internet of Things. These advanced technologies allow the Internet to provide enhanced services through sensors, continually monitoring a wide range of information. The paper reviews the most recent studies that implemented fog computing in a 5G environment by defining the essential services and network-oriented functionality. Moreover, the surveyed study is also discussed and assessed through sum-up tables with general remarks about the followed trends. The mentioned studies presented legitimate solutions for issues in the Vehicular Network and improved the current network architecture.
