To overcome the problems of inaccurate positioning and large time consumption for traditional node localisation in wireless sensor networks, a node localisation method based on an improved bee colony algorithm is proposed in this paper. This paper adopts a traditional method combined with a classical multidimensional expansion method to construct a static distance matrix, uses the improved bee colony algorithm to obtain the original coordinates of the static nodes in a wireless sensor network, and determines the actual positions of these nodes. And use the offset speed and a time sequence method to construct an offset compensation model of dynamic sensor nodes. Combined with the uniform measurement method of node target positioning, the optimal positioning of the dynamic sensor nodes is determined. The experimental results show that the accuracy of the proposed method is approximately 98%, and the shortest time is approximately 2.2 s.
