摘　　要：为满足不同业务需求,保障业务实时性与稳定性,针对多种业务不同的链路连通性,提出适合不同业务的链路选择方法。基于航空自组网近似模型,首先提出一种节点到基站的连通概率算法,其次根据飞机非匀速运动特点,运用Gauss-Markov移动模型,求出航空自组网连通时间,同时建立相应场景并进行仿真。结果表明,不同业务可根据程序计算结果选择所需链路。In order to meet the needs of different services and guarantee the real-time and stability of services,this paper proposes dif⁃ferent link selection methods for different services according to varied connectivity of service links.Based on the approximation model of aeronautical ad hoc networks,a node-to-base station connectivity probability algorithm is proposed.Secondly,according to the non-uniform motion characteristics of the aircraft,the Gauss-Markov moving model is used to find the connection time of the aeronauti⁃cal ad hoc networks,and the scenario is simulated.The results show that different services can select the required links according to the program calculation results.
