The past few years have seen an increasing interest in the development of vehicular ad hoc networks resulting in many routing protocols proposals. Scalability issues in such networks are attracting increasing attention these days. To improve data delivery performance in large scale networks, we propose SIFT, a trajectory based routing scheme that requires sparse infrastructure and rely on low quality information. It merely uses the trajectory and the location of the last node that forwarded the packet to forward a data packet from a source to a destination. SIFT is evaluated against DREAM, a well-known routing protocol from the literature through realistic simulations using Omnet++. Simulation results demonstrate that under dense deployment, using a realistic mobility model scenario, the proposed scheme performs better in terms of delivery ratio, end-to-end delay and route length.
