In Vehicular Ad Hoc Networks (VANET), the efficient data dissemination is affected by the critical factors such as connectivity, transmission quality and redundancy elimination. Most of the existing techniques concentrate either on sparse or dense populated vehicular network that increases redundancy. Though existing clustering technique improves the connectivity, there is lack in transmission quality. In order to overcome these issues, in this paper, we propose a cluster based reliable forwarding mechanism for Data dissemination in vehicular networks. In this technique, the multilane two way highway is divided into clusters based on the deployment of road side units. Within the clusters, the node with highest transmission quality is selected as the cluster head based on the transmission quality. The cluster head uses the backfire algorithm for data transmission that minimizes the redundancy in the network. By simulation results we show that the proposed technique minimizes the redundancy and improves the reliability.
