Efficient Inter-Vehicle Internet Content Distribution Based on Named Data

A key challenge in Internet access applications of Vehicular Ad Hoc Networks (VANETs) is the rapid distribution of Internet content to car users with low cost. The content distribution service among vehicles is free, but it is susceptible to frequent interruptions and failures because of the volatile and spotty vehicle-to-vehicle (V2V) channel. To make V2V communi-cations play a positive role in Internet access applications, this paper proposes a simple inter- vehicle one-hop large-size content distribution mechanism that applies the emerging Named Data Networking (NDN) concept to V2V communications and enables multiple functions including nearby request, multisource supply, intelligent response and breakpoint resume to be fulfilled. The realization of these new functions benefits not only from the capabilities of NDN, but also especially from our elaborate designs. Simulation results from the ndnSIM network simulator show that the proposed mechanism can dramatically raise the efficiency of inter-vehicle Internet content distribution compared to mechanisms based on IP or original NDN.
