Spatial Region Query Based on Grouping P2P Network
Wenjun Xie · Jisuanji gongcheng · 2009
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.
