description The invention discloses a method for carrying out multidirectional scaling positioning on a wireless sensor network by distance sensing and belongs to the field of computer communication networks. In the method, according to the characteristics of node positioning in the wireless senor network, a concept of 'correlative nodes' is introduced; and according to the network deployment condition, a one-hop distance matrix of nodes is obtained, distances among multi-hop nodes are obtained, and the distances among the multi-hop nodes are automatically adjusted according to the node deployment condition, so that approximate distances are prevented from being singly applied; therefore, the node positioning accuracy is further improved. The method can be applied to different network scenarios, the node positioning accuracy is further improved and the network deployment resources are saved.
