基于移动预测的高动态飞行器路由算法

High Dynamic Aircraft Routing Algorithm Based on Mobility Prediction

临近空间自组网中一类特殊的飞行器——高动态飞行器,由于具有很高的移动速度,造成网络拓扑变化频繁,传统自组网路由算法难以满足要求.在研究临近空间自组网节点运行特点的基础上,提出了一种基于移动预测的高动态飞行器路由算法,采用按需路由策略,在高动态飞行器的飞行轨迹上设置"路标",通过"路标"指示的路由进行数据传输.利用网络仿真软件NS2进行仿真实验,结果表明,该路由算法具有良好的网络性能,适合应用于高动态飞行器.

As a particular category of aircrafts in near-space ad hoc networks, the speed of highly dynamic aircraft is very high, thus making the network topology change frequently and the conventional routing algorithms of ad hoc networks unable to meet necessary requirements. Studying the characters of nodes in near-space ad hoc networks, a high-dynamic aircraft routing algorithm based on mobility prediction is proposed, which adopts reactive routing policy in accordance to relevant requirements, and sets ＂route marks＂ along the flight track of highly dynamic aircraft to lead the data to be transmitted along the routing marked. The software NS-2 was used to simulate the proposed algorithm, and the result showed that this routing algorithm can provide a good network performance and adapt to the highly dynamic aircraft.
