3D Spatial Analysis Oriented Hybrid P2P Computing

This paper puts forward the approach of building distributed 3DSIS based on hybrid peer-to-peer (P2P) network, and the structure of the distributed 3DSIS P2P network is designed. For performing spatial analysis tasks, the paper also analyzes the communication mechanism of 3D spatial analysis based on P2P computing model and presents the principle of the spatial analysis task division and the scheme of tasks dispatch controlling. Finally, the test system, which has simulated the slope analyzing based on the P2P computing model, is also presented. Compare with the single server (C/S) based slope analysis; the P2P computing based analysis task performs more efficiently and has a better capability of supporting huge amount of requests from the users.
