Ferrying vehicular data in cloud through software defined networking

In Vehicular Ad Hoc Network (VANET), huge amount of data requests are made by the users from the vehicles traveling through a city. The requested data need to be transmitted and processed by the cloud service providers to maintain the quality of service. In this paper, data transmission time is computed when vehicular data is transmitted to the cloud though the road side units and OpenFlow switches in a Software Defined Network (SDN). The proposed scheme allows some sorts of traffic engineering methods that can be used to address the connectivity problems involving transmission delay and packet loss of the vehicles in a smart city. Simulation results show that the proposed mechanism can achieve better packet delivery rate and least round-trip time as compared to similar data transmission protocols.
