基于节点间链路传播时延和链路维持时间建模，提出了一种可实现多业务服务质量优化的飞行自组织网络路由协议，针对链路传播时延和链路维持时间进行了定量分析，从计算视角为路由决策算法提供了支撑。首先利用大地中心坐标系建立节点移动模型，并结合移动模型计算链路传播时延和链路维持时间。其中，链路传播时延为节点间通信距离的函数；链路维持时间计算模型相关参数包括节点间的相对距离矢量、相对速度和加速度矢量。然后，针对三种业务类型构建了相应的差异化路由度量，并以此计算最优路由。仿真结果表明，所提路由协议在保证各业务服务质量的基础上，降低了网络时延和丢包率。

We propose a routing protocol that optimizes the quality of multi‑service provisioning in flying ad hoc networks (FANETs) by modeling the link propagation latency and link duration between nodes. We present quantitative analysis of the link propagation latency and link stability, which supports the routing decision algorithm from the computing perspective. Firstly, a mobility model is established by using the geocentric coordinate system, while the link propagation latency and link duration are calculated with the aid of the mobility model. The link propagation latency is a function of the communication distance between nodes. The relevant parameters in the link duration calculation model include the relative distance vector, relative velocity vector and acceleration vector between nodes. Then, the corresponding routing metrics are constructed for the three services considered, and the optimal routes are calculated based on these metrics. Simulation results show that the proposed routing protocol can reduce the network latency and packet loss rate while ensuring the quality of each service.
