P2P Multi-dimensional Range Query System Based on Kademlia

Structured P2P networks has good expandability,but it is difficult to support multiple keywords query or range queries.This paper analyzes the existing complex query,and proposes a P2P multi-dimensional range query system based on Kademlia which named K-net.When processes multi-dimensional range query,it deals with dimension reduction and range partition simultaneously.This method can reduce the bandwidth required for query.The simulation results show that this system has good query accuracy and expansibility.
