| Abstract: | Based on the P2P EIR-tree framework, the range query and search processing algorithm is improved and adapted to query multi-dimensional dataset on P2P network system. The main idea and realization methods of the range query and search processing policy is discussed. A series of simulation experiments are done to validate the results and confirm the main factors affecting efficiency and data access speed. |
