The invention discloses an Internet of Vehicles roadside unit deployment method and system based on emergency message broadcast, and relates to the technical field of Internet of Vehicles communication. The method comprises the following steps: constructing a message transmission protocol and an urban traffic network model, and generating a roadside unit deployment scheme in the urban traffic network model according to the message transmission protocol; constructing an objective function by taking communication requirements and system cost as indexes according to the roadside unit deployment scheme, solving the objective function by adopting an improved non-dominated sorting genetic algorithm based on an elitist strategy, constructing a comprehensive utility function, and performing evaluation by utilizing the comprehensive utility function to obtain an optimal roadside unit deployment scheme; and deploying the roadside units according to the optimal roadside unit deployment scheme. According to the method for deploying the roadside units of the Internet of Vehicles, the communication requirement and the system cost can be considered in an emergency message broadcasting scene, the overall performance of the system can be improved, and the effectiveness of emergency message broadcasting is effectively improved.

    本发明公开了一种基于紧急消息广播的车联网路边单元部署方法及系统,涉及车联网通信技术领域。该方法包括以下步骤:构建消息传输协议和城市交通网络模型,按照消息传输协议在城市交通网络模型中生成路边单元部署方案;根据路边单元部署方案以通信需求和系统成本为指标构建目标函数,采用改进的基于带精英策略的非支配排序遗传算法对目标函数进行求解,并构建综合效用函数,利用综合效用函数进行评估得到最优路边单元部署方案;根据最优路边单元部署方案对路边单元实施部署。本发明车联网路边单元部署方法的在面向紧急消息广播场景中能够兼顾通信需求和系统成本,能够提升系统的整体性能,有效提高紧急消息广播的有效性。
