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.

摘要： 带状无线传感网为长距离带状分布，现有的数据收集算法无法很好解决其数据收集延迟较大的问题。提出了一种主动定位移动Sink的数据收集算法DCFAN（Data Collection based on Forwarding of Agent Nodes），DCFAN构建移动Sink的同步代理节点以及存储同步代理节点的线节点序列，通过获取同步代理节点转发感知数据到Sink汇聚点。仿真结果表明，DCFAN算法能有效降低网络节点能耗以及数据收集延迟，同时提升数据收集率，适用于对数据收集延迟具有一定要求的带状无线传感网应用场景。
