According to the communication requirements of twenty-four terminals in the wireless Ad Hoc network of the project, in order to make the communication more efficient, it's necessary to choose a routing protocol for mobile topology changes. In this paper, the AODV and AOMDV routing protocol in wireless ad hoc networks are compared and selected. With the specific simulation scenario, the two kinds of routing protocol were tested through the NS2 simulation platform. Experiments show that in the background of project, each performance index of AOMDV was better than those AODV, and was more suitable for the communication of multi node mobility scenarios.%针对项目中24个移动终端需要在无线自组网中进行联网通信的需求，为了使通信效率更高，需要选择一种能够适应节点移动带来拓扑变化的路由协议。文章对自组织网络中的AODV和AOMDV路由协议进行了比较和选择的过程。结合具体的仿真场景，通过NS2仿真平台对两种路由协议进行了协议性能测试。实验表明，在项目背景下，AOMDV的各项性能指标均优于AODV，且更加适合移动场景下多节点的通信。
