摘　　要：针对大规模传感器网络节点异构性突出、调度困难,传统节点调度算法在大规模传感器网络环境下效率低等问题,提出了基于云计算的节点调度模型,并设计了该模型下的节点调度改进算法。通过将节点算法的执行迁移至云端,由云端调度节点。通过OMnet++对改进算法与云端融合数据处理进行仿真实验表明:改进算法可以有效地延长网络生存周期,并且随着数据量的增加,云端处理融合数据耗时相对平稳。相比较传统节点调度算法,改进算法在能量与耗时指标上表现更优。Aiming at problems of nodes heterogeneity prominent,scheduling difficulities and low efficiency of traditional node schedule algorithm in large-scale wireless sensor networks（ WSNs）,put forward a model for nodes schedule and an improved nodes schedule algorithm. Execution of the node algorithm is immigrated to cloud and the nodes are scheduled by cloud. The simulation experiments shows that the improved algorithm can prolong lifetime of networks efficiently and with increasing of amount of data,time consuming of fusion data cloud processing is relatively stable. The improved algorithm works better on energy and time consuming,compared with traditional nodes schedule algorithm.
