摘    要:在具有超级结点的非结构化P2P系统中,研究了复杂多维数据的查询搜索策略,提出了一个应用于具有超级结点的非结构化P2P网络的综合框架,在该框架中,能够实现对多维数据共享、索引以及查询等操作的处理。以R^*-tree索引树为基础,提出了一种能够应用于P2P的扩展R^*-tree索引树,即EIR-tree树,研究了系统中集群信息的收集与维护、EIR-tree树的构建与维护等方法和措施。

关 键 词:非结构化P2P  超级结点  多维数据  数据查询  搜索框架

Abstract:The query and search policy of supporting complex query over multi-dimensional data is researched on the unstructured P2P network with super-peer,and a comprehensive framework is proposed to apply for sharing,indexing,and querying multi-dimensional dataset.Based on the indexing tree of R-tree,a new adaptive indexing tree named Extended Indexing R-tree(EIR-tree) is proposed.All the methods such as the information collected and maintained and the EIR-tree constructed and updated are discussed.
Keywords:Unstructured P2P  Super-peer  Multi-dimensional dataset  Data query  Search framework
