Vehicular clouds: State of the art, challenges and future directions

Cloud computing and Vehicular Communications are profoundly emerging fields towards realization of smart cities. While cloud computing is stage of development, vehicular cloud computing combines the benefits of Mobile Cloud Computing (MCC) and vehicular communications. Recent studies expect that vehicular cloud computing will be the gateway to the future of transportation systems. However, the development process still reveal on several issues and challenges that need to be carefully addressed in such environment. Privacy, service cost and provisioning delay are identified as the most crucial challenges to be addressed. State of the art includes several proposals to address these issues. In this position paper, we will gather and present a comprehensive study of vehicular cloud computing architecture, applications, and approaches. More importantly, we will discuss the current possible services provisioning solutions with their drawbacks, then, we will provide a thorough discussion on the benefits of using the concept of Quality of Experience (QoE) in such environment.
