针对使用定向天线的Ad Hoc网络邻居发现问题，提出一种全定向邻居发现策略。通过在改进的三次握手过程中引入微时隙策略，有效解决了在Ad Hoc网络中存在的冲突问题，提高了通信效率。根据提出的物理层信号检测机制，有效解决了在基于定向天线的Ad Hoc网络中引入的定向隐藏节点和邻居发现困难等新的问题，提高了邻居发现效率。仿真结果表明，相对于传统邻居发现策略，该邻居发现策略的邻居发现时间减少了接近50%，并且该策略提高了邻居发现效率，同时增加了发现的邻居链路数目。

According to the neighbor discovery problem in the Ad Hoc networks, the full directional neighbor discovery strategy was proposed. With the help of mini-slot strategy involved in the progress of three-hands, the problem of collision in Ad Hoc networks was been effectively resolved; as a result, the communication utilization radio was increased. The detection strategy of physical signal was proposed, which resolved the new problem of directional hidden node and the difficulty of neighbor discovery introduced by Ad Hoc network based on directional antenna. The simulation results show that, compared with the conventional neighbor discovery algorithms, the neighbor discovery time of the proposed strategy is decreased almost 50%, also has a better performance and more neighbor discovery links.
