A topology-oblivious routing protocol for NDN-VANETs
share
Vehicular Ad Hoc Networks (VANETs) are characterized by intermittent connectivity, due to the unpredictable mobility of nodes. This leads to failures of end to end paths between nodes, and thus makes the routing decisions a challenge for the community. Named Data Networking (NDN) is a network paradigm that deals with such problems, since information is forwarded based on content and not on the location of the hosts. We propose a topology-oblivious multihop, multipath and multichannel VANET routing strategy that exploits several paths to achieve faster content retrieval. We minimize the broadcasting nature of Wi-Fi by adding new fields to Interest and Data messages (MMM-VNDN) and also, we deployed a second algorithm that performs the forwarding decisions in the strategy layer of NDN (iMMM-VNDN). Simulation results show that our approach does not only guarantee faster data delivery, but also saves network resources, due to reduced message retransmissions.
