摘　　要：航空自组网是自组网在航空领域的典型应用。航空自组网的关键技术在于路由协议的选取和设计。基于场景用NS2软件仿真研究了3种适用于航空自组网的路由协议及其网络性能,并定义了4个性能评估准则。仿真结果表明,单跳距离一定时,3种路由协议的网络性能随着节点密度的增加而总体变差。同等条件下,AODV路由协议路由开销高于DSVD和GRID路由协议,端到端平均延时低于DSVD和GRID路由协议,而GRID协议分组投递率和平均跳数保持最高。Aeronautical Ad Hoc network is the typical application of Ad Hoc network. Selection and design of the routing are the keys of aeronautical Ad Hoe network. Three kinds of applicable to aeronautical Ad Hoc network routing protocol and network performance are studied based on scene simulation with NS2 software. The simulation results show that, when the single hop distance is fixed, three kinds of routing protocols network performance and overall deterioration as the node density increases. Under the same conditions, the AODV routing protocol routing overhead is higher than that of DSVD and GRID routing protocol, the end-to-end average delay below DSVD and GRID routing protocol, and GRID protocol packet delivery rate and the average number of hops to maintain the highest.
