基于P2P网络的AVL索引树范围查询研究

Study of the AVL-index Tree Range Query Based on P2P Networks

  • 摘要: 介绍了一种基于P2P网络环境下的多维数据范围查询的通用架构,构造了一个虚拟的基于空间划分的层次树,以保证相关查询区域的探索尽量发生在同层节点之间,减轻了上层节点的查询负担,从而避免了树根结点的瓶颈问题,有效地降低了更新代价.模拟试验证明了该方法的有效性.

     

    Abstract: This paper introduces a common architecture of the multi-dimensiona1 data range queries based on the P2P network and constructs a virtual hierarchical tree based on space division which ensures that the exploration of the relevant query regions occurred between the nodes in the same layer as far as possible. Thereby the query burden of the upper node will be reduced and the bottlenecks of the root node can be avoided which will reduce the updating cost effectively. Through the simulations the method has been proved to be effective.
