Abstract
Named data networking has been efficiently utilized in Vehicular networks as a promising solution to enable reliable and efficient content retrieval. Vehicular named data networks (VNDN) employ a pull-based mechanism where an Interest packet is broadcast in order to receive the Content. This forwarding scheme mitigates the forwarding of unsolicited content, however, the dissemination of critical data forwarding generated randomly in the network is not considered. For instance, in the vanilla NDN framework any content received by a vehicle is considered unsolicited and dropped provided no corresponding entry is available in the pending interest table of that vehicle. Despite its potential, some modification in the NDN architecture are required to forward the high priority critical content. In this work, we enable the vehicles' NDN forwarding mechanism to reliably share the critical content from different vehicles sources in the networks. The solution is evaluated in NS2 and the findings showthat the proposed scheme is able to collect the data from several vehicles in the networks with reduced network overhead and data retrieval delays.
