摘　　要：移动低占空比无线传感网(Mobile Low-duty-cycle Wireless Sensor Networks,MLDC-WSN)是一种新型的传感器网络,它能克服传统无线传感网络(WSN)中仅考虑静态网络、网络能耗大等问题。但是,MLDC-WSN的新特性给数据收集应用带来了新的挑战,例如:移动性会导致网络拓扑结构不断改变,造成网络连通性不稳定;节点的苏醒时间短,造成通信延迟大。针对MLDC-WSN中数据收集的研究现状进行了分析和对比,分别从节点移动性管理、节点睡眠调度、数据收集协议等3个方面进行了综述。此外,还总结了该领域中待解决的重要科学问题,并对未来的研究方向进行了展望。Mobile low-duty-cycle wireless sensor networks(MLDC-WSN)are a kind of new sensor networks appearing in recent years,which can overcome the drawbacks of large energy consumption in traditional static wireless sensor networks(WSN).However,new features of MLDC-WSN bring new challenges to data collection applications.For instances,mobility will cause network topology to change constantly,which will make the network connectivity become unstable.The nodes in the network only wake up for a small proportion of time,which will increase the communication latency.This paper analyzed and summarized research progress on data collection in MLDC-WSN,and gave in-depth analysis on three main aspects of existing works:mobility management of nodes,sleep scheduling of nodes,and data collection protocols in the networks.In addition,it pointed out several important scientific problems in this field,and discussed future research directions.
