摘　　要：针对移动自组网中移动和活动范围扩大等因素导致网络连通性的变化问题,该文提出一种支持移动自组网通信的多无人机中继网络。通过场景分析与系统建模,定义了地面节点与无人机连通率、地面节点跨域通信连通率、无人机连通率,提出了一种加权质心的单无人机飞行模型,设计了多无人机中继网络的飞行控制方法。仿真分析了地面节点的活动区域、移动速度以及通信业务对3种网络连通率的影响,比较了基于加权质心方法与质心方法在支持网络连通率上的不同。结果表明:加权质心方法在支持地面节点跨域实时通信上的能力要优于质心方法,但前者在支持地面节点与无人机间连通率的能力上要差于后者。Network connectivity can be affected by mobile networks mobility and extensions of the active area.This paper presents a method using an unmanned aerial vehicle（UAV） relay networks to support communication in mobile ad hoc networks.System models are given for ground node to UAV connectivity,ground node to ground node via UAV connectivity,and UAV to UAV connectivity.This paper also presents a weighted centroid UAV flight model with a flight control method for the UAV relay network.Simulations analyze the impact of the ground node active region,speed,and communication methods on the three types of network connectivity.The simulations also analyze the performance of the weighted centroid UAV flight method and the centroid UAV flight method.The simulations show that the weighted centroid UAV flight method more effectively supports ground node intra-domain communication than the centroid UAV flight method while the weighted method is less effective in supporting ground node connections to the UAV.
