摘　　要：讨论了拓扑控制的目标,利用随机图理论研究了无线传感器网络拓扑控制的模型及代表性算法;基于网络结构的不同,分析和比较了无线传感器网络中各种拓扑控制机制的特征;深层剖析了无线传感器网络拓扑控制与连通、调度之间的关系;最后对拓扑控制亟待解决的问题进行了总结和展望。As a vital supporting technology in WSNs, topology control can reduce redundancy and prolong network lifetime on the premise of network coverage and connectivity. This paper discussed the target of topology control, studied topology control models in WSNs and typical algorithms with the application of random graph theory, made comparative study of the characteris- tics of topology control mechanism on the basis of different classifications of network structure, and explored the relations among topology control, connectivity and scheduling in WSNs. Finally, it summarized the present situation and problems which still remained to be solved.
