Static wireless network sensor does not consider the mobility problem of nodes in the design process, which leads to the current node location method cannot meet the needs of dynamic wireless sensor network positioning. Aiming at the shortcomings such as low positioning accuracy and long response time of traditional node location strategy, a dynamic node location optimization method is proposed. The method uses the optimized inter-node distance model to optimize the path, and minimizes the estimated area of the unknown node through the rotatable directional antenna mounted on the anchor node so that the estimation of the path is closer to the actual distance. The experimental results showed that the proposed method has better accuracy and stability than the current positioning method.
