英文摘要： With the development of vehicular ad hoc network and mobile communication network, there are more and more applications in the hybrid network of vehicular ad hoc network and mobile communication network. On the one hand, due to high-speed mobile vehicle nodes in vehicular ad hoc network, the network topology changes frequently, the coverage of roadside units is limited, and the placement ratio is low. On the other hand, the bandwidth of mobile communication network is limited, and the cost usage is higher. Therefore, this project investigates how to reasonable deploy and exploit the hybrid vehicular ad hoc network resources, better service to the vehicular ad hoc network applications. This project: Research on hybrid vehicular ad hoc network environment, and proposes heterogeneous node placement algorithm with heterogeneous communication model, heterogeneous coverage and heterogeneous placement cost; Design information transmission model under hybrid vehicular ad hoc network environment, and combined with vehicle nodes, roadside units and infrastructure node; Research on hybrid vehicular ad hoc network environment, exploiting roadside units and infrastructure to aided information transmission technology; Propose a new method of roadside units and infrastructure collaborative content download and distribute under hybrid vehicular ad hoc network environment. Moreover, research results can be directly applied to the application of hybrid vehicular ad hoc network, and have strong theoretical and practical research value.
