为满足航空自组网对路由协议的需要，对DSDV、AODV、OLSR三种路由协议的性能进行了研究。首先利用NS-3网络仿真平台搭建了航空自组网的网络模型，然后在航空通信环境下对三种路由协议进行仿真，并从分组交付率、平均延时、吞吐量、路由开销等指标性能进行比较，最后得出在节点密度小、网络拓扑变化快的航空自组网中，AODV路由协议的性能总体优于DSDV和OLSR路由协议，但还存在着路由开销较大的问题。%In order to meet the demand of aeronautical Ad Hoc network by its routing protocol, this paper studies the performances on such three types of protocols as DSDV, AODV and OLSR. Firstly, the network model of aeronautical Ad Hoc is set up by using NS-3 network simulation platform, next, those three types of routing protocols are simulated under the aeronautical communication environment, and meanwhile, those performance indexes including the packet delivery ratio, average delay, throughput, routing overhead and etc. are compared, and finally it comes to a conclusion that the performance on the AODV routing protocol is better overall than the DSDV and OLSR protocols in the aeronautical Ad Hoc network where its node density is small and the network topology changes fast, while the routing overhead is bigger.
