摘要: 针对传统集中式空间数据应用出现的性能瓶颈以及结构化P2P系统中由于数据的一致性分布而导致的空间数据物理特性丢失等问题,提出一种分组式P2P网络系统,并描述在该网络系统下的数据插入和删除、节点的加入和离开以及空间区域查询。通过仿真验证了其有效性。

关键词: P2P系统, 空间数据, 分组

Abstract: Aiming at shortcomings of performance bottleneck in traditional centralized spatial data management systems and the faults that spatial semantic information can not be retained caused by consistent data distribution in Peer-to-Peer(P2P) systems, a grouping P2P network architecture is put forward, as well as a description of the spatial data operation and peer’s joining and departure in the network. Simulation experimental results verify the architecture.

Key words: Peer-to-Peer(P2P) system, spatial data, grouping
