摘　　要：针对在农田生境监测场景中,无线传感器网络在数据采集时存在数据量小和功耗大的问题,使用移动sink进行数据采集可以改善无线传感器网络的性能。移动sink在无线传感器网络中沿着预定义的路径移动并从附近的传感器节点采集数据,然而由于移动sink的速度过快或过慢导致数据采集量小或传输延迟高。通过优化传感器的数据传输调度和移动sink的速度来确定移动sink的最佳数据采集调度。仿真结果表明,该算法可以提高数据采集量和网络吞吐率。In view of problems of small amount of data and large power consumption in data collection of wireless sensor network in farmland habitat monitoring scene,it can improve performance of wireless sensor network using mobile sink for data collection.Mobile sink moves along a predefined path in WSNs and collects data from nearby sensor nodes.However,due to fixed speed of mobile sink,amount of data collection is small or transmission delay is high.Optimal data acquisition scheduling of mobile sink was determined by optimizing data transmission scheduling and speed of mobile sink.Simulation results showed that algorithm could improve data collection and network throughput.
