摘　　要：传感器网络节点是低功耗低价格微型嵌入式设备,其能量供应和无线通信带宽十分受限。无线传感器网络的拓扑控制用来控制能量高效的合理网络结构的形成,对通信机制、数据融合和时间同步等有重要影响,是无线传感器网络底层关键支撑技术之一。本文从节点功率控制、层次型拓扑形成和网内协同启发机制三个方面,详细介绍和分析了已有典型的拓扑控制算法,并对拓扑控制的研究热点和发展趋势做了总结。The node in sensor network is an embedded device with low-cost and low-price. Its energy supply and wireless communication bandwidth are very limited. The topology control mechanisms can help the formation of the energy-efficient network structure. It also has a major impact on mechanism for communication, data integration and time synchronization. Because of which mentioned above, the topology control is one of the key technologies in sensor network. In this paper, three main catalogs will be discussed, they are node＇ s power control, cluster topology control and the self-configuring and trigger mechanism between nodes. The typical detailed overview and analysis of algorithms have been focused in the discussion; the present hot spots and the future trends on the research of topology control are summarized also.
