The Research of Movement Control Policy on Tiered Mobile Network

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.
