Practical evaluation of the Unmanned Aerial Vehicle (UAV) network requires a lot of money to build experiment environments, which includes UAVs, network devices, flight controllers, and so on. To investigate the time-sensitivity of the multi-UAV network, the influence of the UAVs' mobility should be precisely evaluated in the long term. Although there are some simulators for UAVs' physical flight, there is no explicit scheme for simulating both the network environment and the flight environments simultaneously. In this paper, we propose a novel co-simulation scheme for the multiple UAVs network, which performs the flight simulation and the network simulation simultaneously. By considering the dependency between the flight status and networking situations of UAV, our work focuses on the consistency of simulation state through synchronization among simulation components. Furthermore, we extend our simulator to perform multiple scenarios by exploiting distributed manner. We verify our system with respect to the robustness of time management and propose some use cases which can be solely simulated by this.
对无人机（UAV）网络进行实际评估需要大量资金来构建实验环境，其中包括无人机、网络设备、飞行控制器等。为了研究多无人机网络的时间敏感性，需要长期精确评估无人机移动性的影响。虽然有一些用于无人机物理飞行的模拟器，但没有同时模拟网络环境和飞行环境的明确方案。在本文中，我们提出了一种针对多无人机网络的新型联合仿真方案，该方案可同时进行飞行仿真和网络仿真。通过考虑无人机飞行状态与网络情况之间的依赖性，我们的工作通过仿真组件之间的同步来关注仿真状态的一致性。此外，我们通过利用分布式方式扩展模拟器以执行多个场景。我们针对时间管理的鲁棒性验证了我们的系统，并提出了一些仅可由此进行模拟的用例。
