Blockchain Enabled Data Communication Scheme for Vehicular Named Data Networks

With the tremendous increase in the number of vehicles they exchange of information among them has also increased specifically aimed at road safety. Mostly, the information traveling in this network is important and personal, which brings security and privacy an important aspect during the information sharing. Here, Named Data Networking emerges as a futuristic network architecture that aims to focus on the content rather than the address of the content. Along with this, it provides in-networking caching, security, and adaptive data forwarding features for proving a Quality of Service (QoS) to the network. However, when this is applied on the vehicles termed as Vehicular Named Data Networking, a lot of challenges arise because of highly mobile vehicles. These challenges specifically raised concern towards the QoS and security aspects. The use of a decentralized ledger is required where every data packet can be sent from a verified vehicle only. This ensures that only authenticated and authorized data sources are contributing in the network, thus preventing malicious attacks. In this paper we have proposed a Blockchain enabled Data communication scheme for Vehicular Named Data Networks (BD-VNDN). This scheme provides an authenticated data packet to every interest packet and has been designed for vehicle-to-vehicle and vehicle-to-infrastructure-based communication. To verify the efficiency of the proposed scheme, extensive simulations have been performed on the ndnSim simulator. Different scenarios have been evaluated for the scheme and the results have been analyzed in terms of such as throughput, interest satisfaction delay, and interest success rate.
