Abstract
Vehicular Ad hoc Network (VANET) has recently become one of the highly active research area s for wireless networking. Since VANET is a multi hop wireless network with very high mobility and intermittent connection lifetime, it is important to effectively handle the data dissemination issue in this rapidly changing environment. However, the existing TCP/IP implementation may not fit into such a highly dynamic environment because the nodes in the network must often perform rerouting due to their inconsistency of connectivity. In addition, the drivers in the vehicles may want to acquire some data, but they do not know the address /location of such data storage. Hence, the named data networking (NDN) approach may be more desirable here. The NDN architecture is proposed for the future Internet, which focuses on the delivering mechanism based on the message contents instead of relying on the host addresses of the data. In this paper, a new protocol named Roadside Unit Assisted of Named Data Network or RA - NDN is presented. The Roadside Unit (RSU) can operate as a standalone node (SA-RSU). One benefit of deploying SA-RSUs is he improved network connectivity. The RA-NDN protocol is to reduce the latency under various vehicular entities, vehicular transmission ranges and number of requesters; the existing approach is compared with V-NDN via a real - world data set. The RA-NDN model results show that improves the performance of ad hoc communications with the increase in data received ratio and throughput and the decrease in total dissemination time and traffic load.
