摘　　要：【目的】为了改善基于Delaunay结构的无线Mesh骨干网络拓扑复杂度、通信链路角度以及全向通讯时信号干扰严重等不足,提出一种基于定向通信机制的节点链路角度最优化拓扑控制算法。【方法】该算法通过优化节点通信链路角度,使其相对最大,降低网络拓扑复杂度,并采用定向通讯机制降低通讯链路之间信号干扰。【结果】在满足约束条件下,该拓扑优化控制算法不但使节点链路之间角度控制在相对最大范围,减小了定向通讯时信道的干扰,同时也改善了无线Mesh网络(WMN)的丢包率、延迟、吞吐量等性能。【结论】仿真实验结果表明,该拓扑控制算法是有效的。[ObjectivelIn order to optimize the complexity,communication link and omnidirec-tional communication angle signal interference and serious deficiencies of the wireless Meshbackbone network topology based on Delaunay structure?this paper proposes a topology controlalgorithm based on directional communication mechanism for node link angle optimization.【Methods】First,this algorithm optimized the node communication link angle to make its anglerelatively maximum and reduced the complexity of network topology.Secondly?it used the di-rectional communication mechanism to reduce signal interference between the communicationlink.【Results】Under the constraint condition,the topology optimization control algorithm notonly made the Angle of node links the largest?reduced the signal interference of directionalcommunication,but also improved the WMNnetwork packet loss rate?delay and throughputperformance.[Conclusion】The simulation exper-iment results showed that topology control algo-rithm was effective.
