基于多属性最优化的海洋监测数据布局策略研究与分析

Research and analysis of marine monitoring data layout strategybased on multi-attribute optimization

海洋监测数据的大规模、强相关性和实时更新特性给海洋应用中的数据的快速存储和查询带来了巨大的障碍。为此,本文提出了一种多属性优化布局策略,可以提高数据的利用率和海洋应用的查询效率。多属性优化方法用于对影响存储节点的关键属性进行决策分析,并为每个数据副本布局找到具有每个属性的最佳节点。实验结果表明,该策略有效地管理和安排了数据副本。

The large-scale,strong correlation and real-time updating characteristics of marine monitoring data bring huge obstacles to the rapid storage and query of marine application data.Therefore,this paper proposes a multi-attribute optimization strategy,which can improve the utilization of data and the query efficiency of marine applications.The multi-attribute optimization method is used to analyze the key attributes that affect the storage node,and find the best node with each attribute for each data copy layout.Experimental results show that the strategy effectively manages and arranges data copies.
