Implementation and Performance Evaluation of Name-based Forwarding Schemes in V-NDN

Vehicular networking has recently gained great attention. Although TCP/IP protocol has shown great resilience over the years, still it is quite challenging in highly vehicular environments. Recently, researchers proposed the use of a content-centric approach, Named Data Networking (NDN), for enhancing the efficiency of vehicular ad-hoc networks. NDN uses application generated variable-length, location-independent names to retrieve and/or disseminate the content efficiently. Naming allows NDN applications to access multiple network interfaces at the same time without the need of acquiring IP address repeatedly. In this paper, we implement IP-based data forwarding schemes, such as Epidemic, Spray & Wait, and Adaptive Forwarding using NDN on the sparsely-connected real vehicular testbed. We also evaluate these NDN-based forwarding schemes to study the performance of name based forwarding for retrieving and disseminating data. Our experimental results obtained through real vehicular testbed validate the performance and usability of NDN over VANET.
