A type of data gathering method based on one mobile Sink moving along the fixed traverse points (DGFP) is proposed in this paper. An optimal trajectory for the mobile Sink is built with the help of sensing and coverage models of the sensor node. Moreover, a sleep scheduling strategy is executed to further reduce energy consumption on idle listening. Sensors could go into light sleeping or deep sleeping mode when the Sink is far away from their communication ranges. Simulation results show that, DGFP could not only enhance network coverage, but also balance energy consumption compared with VNP, RP-UG and MobiCluster methods.
