Name Data Networking (NDN) is an instance of information centric network that is based on content-centric networking instead of the traditional host-centric networking. NDN provides a pull-based mechanism to acquire data from the producers. However for the critical data generated randomly in the network, the pull-based mechanism suffers high delays. In this paper, we present an analysis of push-based critical Vehicular NDN (Push-VNDN) and the challenges it faces. Additionally, an improved Push-VNDN scheme is proposed that overcomes the collision and flooding problems faced by the Push-VNDN scheme. Our results show that the iPush-VNDN scheme proves to effectively disseminate the critical data in the network while minimizing the number of data packets forwarded and interest satisfaction delay.

Keywords: named data networks (NDN), vehicular networks, critical data, pull-based data forwarding, push-based data forwarding
