ABSTRACT
The emergence of Internet of Vehicles (IoV) has enabled the interrelation and intercommunication among numerous ubiquitous vehicles, which resulted in an un-precedented generation of heterogeneous and large amount of data. The researchers have not fully explored the various research issues in IoV network despite rapidly increased usage of vehicular fog banks in several areas through last few years. In this context, this chapter presents a comprehensive review on vehicular fog banks for next-generation connected traffic in IoV environment focusing on performance metrics-based studies. The performance metrics-based fog computing techniques for next-generation connected vehicular environment have been categorically described focusing on their limitations and technical contributions while considering various research metrics. The fog computing techniques suggested by researchers have been categorized based on three performance metrics existing in the research area of next-generation connected traffic. Specifically, significance of vehicular fog banks for next-generation connected traffic is highlighted. Following the performance metrics-based fog computing taxonomy, a technique-based qualitative review is carried out on various research challenges raised in next-generation connected vehicular environments while focusing on main functional components, weaknesses and strengths. The open research challenges related to vehicular fog banks for next-generation connected traffic in IoV environment are identified as future research directions in the area.
