Abstract:

The integration of sensors and units in vehicle manufacturing is constantly increasing the data volume generated by vehicles. This requires to support services to handle these data and provide a continuous response to application requests such as collision warnings, lane changing, traffic information, routing information, multimedia streaming, and many others. Add to that the need for achieving the required quality of service is of immense importance. Fog devices deployed along the road are used as a solution to service vehicles. Vehicular ad hoc network (VANET) environment have the property of dynamically changing its cluster connectivity because of the different mobility patterns, which makes it a challenge for vehicular users to access their services. Many preliminary works proposed the use of Software Defined Wireless Network (SDWN) in VANET. In this paper, we study and analyze the use of SDWN in vehicular fog computing environment taking into consideration the suspected high delay between the SDWN controller that is located on the cloud and its switches, the high traffic coming to the controller, the high vehicle speed, and the range of RSU coverage. We have used Mininet-Wifi to implement a vehicular fog computing architecture and simulate different scenarios. Obtained results showed that using SDWN in a VANET environment might not be the best solution in many cases.
