Performance Comparison of a Position-Based Routing Protocol for VANET

VANET is an application of a mobile ad hoc network to inter-vehicle communication. Each vehicle is aware of its position information by GPS or other methods. Position-based routing is a useful approach in VANET. The Position-based routing protocol can be classified roughly into a next-hop forwarding method and a directed flooding method. We evaluate performance of both methods by analysis and simulation and compare them in this paper.
