摘　　要：干扰是严重影响Ad Hoc网络吞吐率的主要原因之一.总结和分析了Ad Hoc网络领域已有的拓扑控制算法方面的研究成果,通过仿真实验比较几种典型干扰优化拓扑控制算法特性,指出现有干扰优化拓扑控制算法的不足,阐述如何从拓扑控制角度来控制网络瓶颈节点数目,同时权衡稀疏化与瓶颈节点数的必要性.研究表明,通过稀疏化优化节点对之间的干扰和通过瓶颈节点控制并降低网络中瓶颈节点数目,不仅可以优化网络干扰,而且从一定程度上提升现有的路由算法效率.Ad Hoc interference is one of the main causes influencing the network throughput rate. This paper summarizes and analyzes the existing topology control research achievements in the Ad Hoc network domain. By the computer simulation experiment, the paper compares several typical interference topological optimization control algorithms, and also points out the current characteristics of the interference topological optimization control algorithm. From the viewpoint of the topological control, the necessity to control the network bottleneck node number, the sparse balance and the bottleneck nodes are discussed. The research shows that through, the optimization of sparse nodes between interference and through the bottleneck nodes in the network control reduced the number of the nodes in the bottleneck, not only optimizing the network interference, but also, to a certain extent, improving the existing routing algorithm.
