摘　　要：为了改善无线Mesh骨干网络全向天线通讯机制所带来的严重信号干扰问题,提出一种基于定向天线的无线Mesh网络拓扑控制技术。首先,采用GG模型建立Mesh网络拓扑,简化拓扑结构,从而有效地降低骨干网络拓扑复杂度;其次,采用定向天线通讯机制,从通讯角度上控制信号传输方向,进而降低信号干扰范围;最后,采用功率控制技术调整发送功率,降低信号通讯距离,减小信号干扰范围。仿真实验结果证明了拓扑控制技术和功率控制技术相结合的有效性。In order to improve serious signal interference of wireless Mesh backbone network due to omni -directional antenna communication mechanism, a topology control technology in Mesh network based on directional antenna is proposed. First, this method used GG model to build topology to reduce complexity of backbone network topology. And then, utilized directional antenna communication mechanisms to control transmission direction of signal, reducing interference of communication. Finally, used the power control technique to adjust the transmission power to decrease communication distance and reduce the range of interference. The simulation results also indicate the validity of the topology control combined the power control.
