In the process of wireless sensor network location based on mobile anchor nodes, the location strategy of mobile anchor nodes has important influence on the performance of positioning. However,the existing strategy does not traverse empty area effectively, the length of path is too long. Therefore, a dynamic adjustment location strategy based on virtual force is proposed. Firstly, the unknown nodes randomly distributed in the region are adjusted to be evenly distributed under the influence of virtual force. Then a moving anchor node travels from the positive center of the region along the direction of equidistant spiral and adjusts orientation dynamically under the influence of virtual force. The simulation results show that the anchor node can traverse effectively according to the unknown node’s distribution, and successfully shorten the length of moving path.
