Because of its characteristics ,Ad Hoc network appears to have received extensive attention ,especially from the military field ,has been widely studied and applied .In some special military applications ,the moving direction and mov‐ing speed of nodes have great relationship with the military requirements ,which led to the network topology changes in real time .In such a tactical Ad Hoc dynamically changing networks ,how to provide better routing services to ensure timely and accurate delivery of information is an urgent need to address the problem .To address this issue ,the characteristics and the main factors of Ad Hoc network routing reconstruction are decribed and a new shortest path routing selection algorithm based on the hop and bandwidth is proposed .Experiments show that the algorithm can select a new link to the destination node when routing reconstruction ,thus ensuring the command operations information transmission smoothly of tactical Ad Hoc network environment .%由于 Ad Hoc 网络的特点，从它出现就一直受到了各界的广泛关注，尤其是在军事领域中，得到了广泛的研究与应用。在一些特殊的军事应用中，节点的移动方向以及移动速度都与作战需求有很大的关系，这导致网络拓扑结构实时变化。而在战术 Ad Hoc 网络这样一个动态变化的网络中，怎么样提供更好的路由服务、确保信息及时准确的送达是一个迫切需要解决的问题。针对这个问题论文主要介绍 Ad Hoc 网络路由重构技术的特点和主要因素，并在原有路由重构算法的基础上提出一种基于路径跳数和带宽的最短路径路由选择算法，通过实验验证，该算法能在网络拓扑结构发生变化触发路由重构时，有效选择一条到达目的节点的新链路，从而保证战术 Ad Hoc 网络环境下，指挥作战信息的畅通传输。
