自适应波束天线由于其发射接收具有强指向性的特点，其网络拓扑控制问题、方法与全向天线存在较大不同。针对节点安装有多个空间均匀分布的自适应波束天线进行组网通信时的拓扑优化控制问题，建立了自适应波束天线和网络节点通信的数学模型；对拓扑优化控制的问题进行了分析，其问题本质是对节点安装的多部天线进行最优化链路分配。以网络通信质量的量化计算作为目标函数，提出了一种基于0-1规划的拓扑控制优化模型，并对网络连通性进行了分析，给出了两节点连通以及整个网络连通的充要判决条件。最后给出了2种不同节点数情况下的仿真计算结果，并通过穷举法验证了模型计算结果的正确性。

Adaptive beam antenna has the characteristics of the strong direction in transmitting and receiv-ing.Its topology control problem and methods are different from non-directional antenna in wireless net-works.To solve the topology optimizing problem based on network nodes installed multiple adaptive beam antenna by spatial uniform distribution,an antenna model and a node communication model are estab-lished,and then the optimized topology control problem is analyzed.The key problem is to decide antenna assignment to achieve the best network communication quality.Based on this,a model of 0-1 programming is proposed for maximum network communication quality,then the connectivity of two nodes and the net-work connectivity are analyzed.Finally,the experiments of different node numbers are given,and the cor-rectnesses of the results are validated by an enumerable method.
