移动自组织网络路由协议多是基于双向链路提出，而单向链路在战场环境下普遍存在，严重影响着网络性能。
Mobile AD hoc routing protocols are designed based on bidirectional links, but there are many unidirectional links in battlefield environment, and they have bad effect on the routing protocols.
首先，通过双星定位系统双向链路获取定时定位信息，将双向测距数据及时问同步误差数据进行处理、保存；
At first, synchronization information from the Tow_stay located system, disposes and saves the data of synchronization time and distance detacted.
如果找到的路由不是纯双向链路，则源节点还需要将RACK报文沿找到的回路路由循环一次，通过RACK的传播来通知中间节点建立起相应的路由。
If it is not a pure two-way path which includes some asymmetric links, the source needs to spread the RACK along the route and inform the route-related nodes to establish the corresponding route.
