Heterogeneous vehicle network, which integrates cellular network with dedicated short-range communication network, is an effective solution for meeting the communication requirements of the intelligent transportation system. Aiming at the diversity of network applications and harsh environment, and multiple network physical media fusion demand, this pasper mainly puts forward a new link scheduling algorithm in LLC layer (LLCA) based on the vehicle risk estimation and event-triggered mechanism to control and schedule the link resources of heterogeneous vehicle networks. Firstly, after establishing the vehicle-risk-field model and estimating the vehicle risk state, the real-time sending frequency of the WSM data is derived. In order to provide the theoretical basis for data packets to select links, the upper bound of the non-WSM data largest distribution frequency of IEEE 802.11p link is given according to the Pareto optimality. Then, based on the upper bound of the maximum non-WSM distribution frequency and IEEE 802.11p link, LLCA algorithm is designed. Meanwhile, the theoretical analysis of time complexity of the algorithm is implemented. Finally, the simulation results show that the proposed LLCA not only reduces the transmission delay of WSM data for secure applications, but also improves the utilization of links on the premise of satisfying most of the QoE network applications.
