摘　　要：本文提出了一种适用于星载设备的改进混合路由协议。以ZRP协议框架为基础,在区域内使用表驱动路由协议,在区域间使用按需路由协议。表驱动路由协议选择经典的DSDV;按需路由协议是路径选择的关键步骤,通过仿真软件NS2对代表性协议AODV和DSR进行仿真,通过分析分组投递率、平均传输延时和路由开销这三个重要指标的仿真结果选出最适合的一种协议。This article propose an improvement mixed routing protocol which is suitable for space-borne equipment. The protocol based on ZRP frame and uses table driven routing protocol in the group,uses on-demand routing protocol between groups.The result of table driven routing protocol choice is the classical DSDV. For on-demand routing protocol is the key step in the path selection,it is necessary to emulate the two typical protocols AOI）V and DSR through NS2.By analyzing the packet delivery ratio, and routing overhead,chooses one suitable protocol.
