摘　　要：摘要：首先，主要针对泛在无线网络的复杂性和异构性等特点，介绍分布式态势感知这一新颖的态势感知理论；然后，通过分析分布式态势感知与集中式态势感知的区别，指出分布式态势感知的6大特点；再次，详细分析分布式态势感知理论的3个主要部分：获取各个部分的认知信息，提取认知对象，表述认知对象与它们活动之间的关系。最后，指出当前分布式安全态势感知技术研究中需要注意的问题。Firstly,according to the complexity and heterogeneity characteristics of ubiquitous wireless network, the distribu- led seeurity situation technology an（I a new situation awareness theo~ are introdueed. Then, thn）ugh the analysis of the difference between distril）uted situalion awareness and centralized situatiun awareness, the authors point out 6 major charae- leristics of the distributed situation awareness. Thirdly,we analyze in detail the three main parts of the distributed situation awareness theory：one is the acquisition of cognitive information,the others are extraction of cognitive objeet and describing lhe relationship between cognitive objects and their activities. Finally,they point out that there are still some problems which need researchers to study about distributed security situation awareness technology.
