Study of Vehicular Cloud during traffic congestion

The Vehicular Ad-Hoc Network has many advantages in the development of road infrastructures and the field of technology. Recently, many research groups suggest to apply the concept of Vehicular Cloud by leveraging the under-used physical resources of cars. In this paper, we discuss the exploitation of vehicular storage capabilities during a traffic jam. We propose a scheme which permits to create a Vehicular Data Center (VDC) on a road segment (RS). Each participated car will contain a specific data item during its residence time on the RS. Once it will leave the RS, a local retrieval should be executed. So, each leaving car will transfer its content to the newly arrived car on the RS and so on. This process will continue so that data items can be available on the RS. But to maintain the data transfer cycle, we have to study some constraints: The participation of drivers, the storage capability of the available car, the existence of an empty car and the transmission time issue.
