Abstract: Vehicular Ad-hoc Network (VANET) is the form of mobile ad-hoc network (MANET) in which the movement of vehicle is restricted by direction of road and traffic regulation. Real-world applications of vehicular communications are restricted due to rigidity in the deployment of protocol. To cover up this limitation in VANET, Software Defined Network (SDN) should be used for better utilization of channels and wireless resources. Due to dynamic nature of vehicles, finding and maintaining data dissemination is essential. Various applications uses different data from different sources, but for short period, high speed vehicles lives in the locality of road side unit (RSU) which results in latency issue. Therefore, to reduce delay scheduling of data is important so that it can serve as much requests as possible. The paper aims to implement SDN architecture along with flow management and Cooperative Data Dissemination (CDD) algorithm which will increase the speed of data dissemination. The performance of proposed algorithm is analyzed on the basic of parameters such as service ratio, service delay and gain of scalability. System performance is improved by improving CDD with peer to peer network.
