The invention belongs to the technical field of mobile communication, and particularly relates to a vehicle cooperative task unloading method in VEC, comprising: establishing a system model including a host vehicle, computable vehicles and non-computable vehicles; establishing a communication model according to the total time required for task unloading from the host vehicle to the computable vehicle; establishing a vehicle selection model based on a plurality of dynamic factors; establishing a task unloading optimization problem based on constraint conditions based on the communication model and the vehicle selection model; the task unloading optimization problem is solved through an analytic hierarchy process and a KM algorithm, and the optimal task unloading condition is obtained; according to the method, dynamic index factors of various edge nodes are fully considered, priority ranking is carried out on the computable vehicles, dynamic matching is carried out on the tasks by adopting the KM algorithm, the total calculation time of the tasks is effectively shortened, and the failure rate of task unloading is reduced.

    本发明属于移动通信技术领域,具体涉及一种在VEC中车辆协同任务卸载方法,包括:建立系统模型,所述系统模型包括主车辆、可计算车辆和不可计算车辆;根据主车辆到可计算车辆上的任务卸载所需要的总时间建立通信模型;基于多种动态因素,建立车辆选择模型;基于通信模型和车辆选择模型建立基于约束条件的任务卸载优化问题;通过层次分析法和KM算法对任务卸载优化问题进行求解,得到最优的任务卸载情况;本发明充分考虑多种边缘节点的动态指标因素,对可计算车辆进行优先级排序,并且采用KM算法对任务进行动态匹配,有效减少任务的总计算时间并降低任务卸载的失败率。
