This paper analyses the performance of a new routing protocol for vehicular delay-tolerant networks, called GeoSpray. This geographic routing protocol performs a store carry-and-forward, combining replication and forwarding/routing decisions based on location information, with explicit delivery acknowledgments to improve network resources utilization. The performance of the proposed routing protocol is evaluated through simulation. The results have shown that GeoSpray achieves higher delivery ratios and lower delivery delays with a considerably low communication overhead, compared to six well-known routing protocols for delay-tolerant networks.
