摘　　要：In city environment, the vehicle communi- cation is affected by the around obstacles due to the espe- cial condition of wireless channels. However, most of prior works adopt the fixed radio range value of vehicles to trans- mit packets. In this paper, we design an optimization for- warding range routing protocol for VANET in urban area. It has an optimized and adjustable forwarding range, which changes with different environments based on the path loss and the city model. And the proposed geo-routing protocol has a novel idea in computing the connectivity of roads and the adjustable strategy in a sparse network. Simulation re- suits indicate that the OFRR enjoys desirable performance in the urban area.In city environment, the vehicle communication is affected by the around obstacles due to the especial condition of wireless channels.
