传感器网络中的节点是一种低成本、低价格的嵌入式设备。它的能源供应和无线通信带宽非常有限。拓扑控制机制有助于形成节能的网络结构。它还对通信机制、数据集成和时间同步产生了重大影响。正因为如此，拓扑控制是传感器网络的关键技术之一。本文主要讨论了节点的功率控制、集群的拓扑控制以及节点之间的自配置和触发机制。重点对典型算法进行了详细的综述和分析，总结了当前拓扑控制研究的热点和发展趋势。
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.
