A Grid Geo-spatial Database System Model Based on Layered P2P Protocol

    Graphical Abstract
    • Abstract
  • Aiming at the faults of conditional geo-spatial database and their new characteristics,a new and high efficiency model—GPeer-SDBMS is proposed.The P2P protocol-Tapestry is employed in this model for constructing a layered distributed geo-spatial database flexibly;and the grid database nodes are divided into many virtual node clusters according to database mode of these nodes.The GPeer-SDBMS model can not only realize distributed storage for geo-spatial data,but also improve the query arithmetic.The experimental result shows that high performance can be acquired very easily and the corresponding system can balance network load efficiently and adapt to complex grid based geo-spatial database environment for its dynamical expanding.
