Abstract: Band-type wireless sensor networks have the characteristic of long-distance banding distribution, so the existing data collection algorithms cannot solve the problems of its long data collection delay. The paper proposes a data collection algorithm DCFAN （Data Collection based on Forwarding of Agent Nodes） with actively positioning the mobile Sink. The DCFAN constructs the synchronous proxy node for mobile Sink and the line node sequence that stores the synchronous agent node. The sensing data is forwarded to the Sink by the synchronous agent node. Simulation results show that the proposed algorithm can efficiently reduce energy consumption of nodes and data collection delay, and also improve data collection ratio. The algorithm is suitable for the application of banding wireless sensor network which has requirements for data collection delay.
