A Link-Stability-Based Interest-Forwarding Strategy For Vehicular Named Data Networks

In recent years, the Vehicular Named Data Network (VNDN) architecture has been proposed to face performance and reliability challenges from IP/host centric Vehicular Ad hoc Networks. The constant mobility of nodes in such networks can result in rapid flooding of unsatisfied interest packets thus leading to network overloads. In this article, we proposed LSIF, a Link Stability-based Interest Forwarding strategy that relies on predictions of link durations to reduce the number of interest and data packets. The simulation results revealed LSIFs benefits. It outperformed existing approaches in both urban and highway VNDN scenarios by significantly reducing interest and data packets but preserving good levels of interest satisfaction rates and low round-trip times.
