%X This article presents a performance analysis between two location-based routing protocols: SIFT (Simple Forwarding over Trajectory), a novel, scalable, spatial-aware, trajectory-based approach, and DREAM (Distance Routing Effect Algorithm for Mobility), a stable, largely tested position-based scheme. The study was accomplished under a realistic urban mobility model for VANETS (Vehicular Ad hoc NETworks), within a highly deployed evaluation network of up to 1000 nodes. Classical ad hoc routing schemes do not perform well in VANETS because they were not designed to handle efficiently mobility handicaps. Position-based techniques perform better in dynamic scenarios, but in some highly dynamic scenarios, like VANETS, they do not always perform efficiently. Trajectory-based protocols perform more efficiently in VANETS since they are spatial-aware. We demonstrate that SIFT performs better than DREAM in a realistic VANET scenario concerning delivery ratio, control overhead, delivery delay, and route length.
