| 摘要: |
| 空中骨干网络由多个空中平台通过无线连接构成，并能够为各类中小型空中平台提供
网络服务。空中骨干节点具有动态性,造成骨干网拓扑结构具有可变性，采用商用路
由协议将会造成网络开销过大、无法维护正确的网络拓扑信息等问题。通过对空中骨干网络
特点进行分析，在商用主动式路由算法的基础上进行跨层设计，并优化泛洪机制，实现了网
络
开销随着链路状态进行动态变化，利用较小的网络开销来维护准确网络拓扑结构。仿真结果
表明，改进的路由协议基本满足空中骨干网的要求。 |

| Abstract: |
| Air backbone network is composed of many air platforms which are conn
ected by wireless communication and can provide network service. The mobility of
air platforms causes variability of network topology. If it uses commercial rou
te protocol, route overhead will be large and network topology information can b
e wrong. Through analysing the characteristic of air backbone network,cross
-layer design and flooding process optimization are performed based on commercia
l route protoc
ol. Rou
te overhead can change dynamically according to link state while maintaining cor
rect
network topology.Simulation result demonstrates that the improved route protoco
l meets the requirement of air backbone network. |
