Abstract
In the mobile sink based sensor networks
the energy consumption issue becomes the key point because of energy constraint on sensor nodes.We established a maximizing minimum probability of energy consumption model
and gave a strong mathematical proof.We also proposed a maximizing minimum probability of energy consumption (MMPEC) data collection algorithm based on this model.MMPEC optimize the length of path distributed between child nodes and the aggregation nodes
and achieves low energy consumption of the whole network.The simulation results show that MMPEC is far superior to other hierarchical data collection methods based on a mobile sink in energy consumption.
