Analysis and improvement on Chord protocol for structured P2P

The key problem in P2P network is effectively to locate resources. Chord has been widely used as a routing protocol in structured P2P networks, but there is a lot of redundant information in the node's finger table. By analyzing Chord protocol, an improved Chord algorithm is proposed in this paper. Analysis on theory and simulation results show that the improved finger tables reduce redundancy and improved Chord algorithm has better performance.
