摘　　要：无人机自组网是对移动自组网的空天扩展,其高机动的飞行特性和网络高迁移性的特点,为移动自组网提出了一个具有挑战性的环境。论文提出在三维空间仿真模型中,针对无人机集群飞行高迁移性的特点,使用基于内存的三维高斯-马尔科夫移动模型模拟高动态无人机节点,对几种常用的移动自组网路由协议进行仿真,分析在高拓扑变化和高移动速度场景下各协议性能表现。最后仿真结果表明OLSR协议能在复杂的网络环境下相比其他协议保持较出色的适用能力,但其时延会随网络负载增加而增加,还需进一步优化。The UAV Ad hoc network is an aerospace extension to the mobile Ad hoc network(MANET).Its highly maneuver⁃ing flight characteristics and high network mobility feature present a challenging environment for the MANET.In this paper,the memory-based 3D Gauss-Markov model is used to simulate high dynamic UAV nodes mobility.Several commonly used MANET routing protocols are simulated and the performance of each protocol is analyzed under the scene of high topology change and high-speed node movement.Finally,the results show that the OLSR protocol can maintain better applicability compared with other protocols in complex network environments,but its delay will increase with the increase of network load,which needs optimization.
