A Spatial Data Management Method Based on Hybrid Peer-to-Peer Networks

Spatial data usually managed by many different custodians and need to be accessed by others. The trait of highly heterogeneous of data management nodes could be well utilized to meet the above application requirement. We use a hybrid peer-to-peer overlay of double layer to present a spatial data management method in distributed wide area network environments. The method fits well with the current spatial data management mechanism. It is provided with the capability of complex spatial query that are usually only supported in unstructured peer-to-peer networks, and it has the strength of effective querying and good scalability. We also introduce a spatial index based on Hilbert space filling curve. The results of simulation experiments show that the method is efficient.
