摘　　要：研究了一类分布式测控网络,分析了网络节点出现故障时网络连通性变化的特点,提出以网络平均度变化最小作为网络重构目标,给出一种基于平均度变化最小的分布式测控网络重构策略,并将其用于网络重构.研究结果表明,该方法在分布式测控网络无法恢复原有结构的情况下能实现网络的连通性重构,并可应用于一类航空航天测控网络.A kind of distributed test and control network is studied. By analyzing the change of the network connectivity when the nodes fail, the minimum average degree of varying network is suggested as the aim of reconfigurating network. What follows is a new network reconfiguration strategy and its application. Finally, this strategy is proved to be effective in connectivity of reconfigurating network when the former structure of the network can not be recovered. Besides, it＇s valid in an aviation and aerospace test and control network.
