V2X task offloading, which moves computational tasks to nearby edge nodes (ENs) with available computing resources, has attracted attention. The task is offloaded to ENs that satisfies the task delay constraints, including the transmission delay and the calculation delay when the task is offloaded. However, since many existing methods assume a static environment in which nodes are fixed, communication may be disconnected in the dynamic environment in which nodes move. On the other hand, the task offloading methods in a dynamic environment, they do not consider the case where the node turning behavior, since they assume only the case where the nodes move in a straight line. Therefore, in order to establish appropriate ENs selection method in dynamic environment, we propose a V2V task offloading method considering automobile behavior including both going straight line and turning in urban area. And the effectiveness of the proposed method is shown in comparison with the existing method by simulation.
