摘要：The localization accuracy of the wireless sensor network node is improved by introducing the virtual anchor node, so the virtual anchor node is constructed and applied by many researchers to optimize the localization algorithm further. This paper presents the broad definition of the virtual anchor node and indicates its significance in the wireless sensor network node localization; the wireless sensor network node localization algorithm based on the virtual anchor node is introduced mainly in two aspects of constructing the virtual anchor node and its application in localization. The scheme for constructing the virtual anchor node includes the random construction method, the geometric constraint method, the node upgrade method, the network training method, etc. And the scheme for its application in localization includes the model reconstruction method, the rank sequence method, etc. By making a concrete analysis of the localization scheme based on the virtual anchor node, its future research prospect and its application development trend are put forward.
