摘　　要：无线传感器网络在物联网中起着关键性的作用,分析已有的网络拓扑管理模式,有助于设置更适合的、满足应用场合需求的管理策略。无线传感器网络依据其拓扑形式分为层次型和扁平型结构;从节点变化角度来分类,分为静态网络与有动态因素的网络(简称为动态网络)。分析了静态网络的层次型结构的选择方式,其簇头的选择方法分为基于概率、非概率以及选择针对性能指标的处理方法;分析了动态网络从供能与否,节点移动与网络移动中网络拓扑管理模式;最后分析了无线传感器网络问题的转化形式,并对转化后的问题的处理做了简要的分析。我们认为,运筹学与博弈论方法是路由设计的有效理论工具。Wireless sensor networks play a key role in the Internet of things. Analyzing the existing topology managements is helpful in both setting more suitable management strategies and meeting the needs of applications. In terms of the topology, wireless sensor networks can be divided into hier-archical structure and flat structure. There are two kinds of wireless sensor networks. One is static network, and the other is dynamic network. We analyze the methods of hierarchical structure built on static network. Three ways are adopted to select cluster heads. The first is based on probability, the second is based on nonprobability and the third is according to performances of networks. By analyzing the dynamic characteristics, we describe the mode of network topology management. Finally, we analyze the transformation forms of wireless sensor networks and make a brief analysis of the transformed problems. We believe that operational research and game theory are effective theoretical tools for routing design.
