Movement control policy has been researched, there exists work in the condition that mobile nodes added on traditional fixed nodes collection pattern. However, a tiered mobile network with nodes floating at random direction and movement track is un-know has not been addressed. We proposed for the first time the triangle-grid movement control model and obtain two important lemmas. Combing the lemmas with improved angle-multidimensional scaling algorithm and minimum velocity algorithm, we designed a classified movement policy of sink nodes to advise the velocity of sink-connect and track of sink-collect. From the simulation, it obviously indicate that this project movement control strategy suits extremely in the large-scale wireless sensor network, when the network scale achieves certain degree, it can show the more superior performance in data collection. The proposed model provides a good solution of the problem on tiered mobile network of instable communication and high-fraction of event loss.
