With the rapid technological advancement, the On-board Units (OBUs) in vehicles are becoming powerful. Besides supporting infotainment and managing vehicle safety, researchers are envisioning that the OBUs of vehicles would be able to offering a utility model of computing (i.e. processing power and storage as a service) to the end users residing in access network segment. Such an ambitious approach seems to be very realistic. The vehicles together with dedicated Fog-computing facility will leverage the computational and storage ability significantly. Some studies impart that 95% time of throughout a day vehicles are remained parked. In some recent research efforts, parked vehicles have been considered as a part of Fog-computing infrastructure-they have been referred as Vehicular Fog Computing (VFC) facility. In this paper, we aim at evaluating TCP throughput performance in a VFC facility. We consider AODV, DSR and AOMDV in our performance evaluation conducted using NS-2 simulator. For the mobility model as an input in the simulator, we consider SUMO generated traffic mobility traces. Findings based on simulation demonstrate that AODV offers the highest throughput among the compared protocols. Aside from this, in this paper, we provide insightful discussion that would open up new research avenues in order to improve performance of TCP in a VFC.
