摘　　要：Vehicular networks have traditionally been used in specific scenarios, such as Electronic Toll Collection （ETC）. New vehicular networks, however, support communication of safety information between vehicles using self-organized ad-hoc technology. Because of limitations in network architecture, current vehicular networks only provide communication for mobile terminals in a vehicle cluster. Vehicles cannot exchange information with an Intelligent Traffic System （ITS） control center nor can they access broadband wireless networks. This paper proposes a novel heterogeneous vehicular wireless architecture based on Wireless Access in Vehicular Environment （WAVE, IEEE 802.1 lp） and Worldwide Interoperability for Microwave Access （WiMAX, IEEE 802.16e）. A new network infrastructure and system model is introduced, and key technologies are discussed. For WAVE, these technologies include adaptive multichannel coordination mechanism and scheduling algorithm; and for WiMAX, these technologies include group handover scheme and two-level resource allocation algorithm.Vehicular networks have traditionally been used in specific scenarios, such as Electronic Toll Collection （ETC）.
