In vehicular networks, the selection of the relay-node determines the message dissemination through the vehicle-to-vehicle communication. However, the irregular shape of the curve road makes it difficult to design and analyze the relay-node selection on the curve road. In this paper, a relay-node selection on the curve road is first proposed, which aims to fast message delivery and complete coverage of the curve road, namely the complete relay-node selection. Additionally, after defining a metric of the curving rate, the models are constructed to analyze the performances of our proposal in terms of the message dissemination speed and the packet delivery rate. Simulations on a realistic mountain road are conducted. Moreover, the up-to-date relay-node selection methods are adapted to suit the scenario of the curve road for the comparison. The results of the simulations prove the validation of the analytic models and the significant performances of our proposal. The attractive benefits include not only the stable performance against the vehicle density in terms of the message dissemination speed and the packet delivery rate but also the improvements of at least 16.20% gain compared with these adapted methods in terms of the message dissemination speed as well as the packet delivery rate of more than 99.7%.
