Research on Improved P2P Chord Model Based on the IP-LCO Algorithm

In order to solve the problem that the structure of P2P network´s logical network and physical topology do not match at a large extent, information of resources´ searching are time-consuming, we propose an improved P2P chord model which was based on the IP-LCO algorithm. The adoption of IPv6 addresses can solve the unmatched problem, and LCO algorithm can quickly location the resources´ network node which had connected with higher probability. The simulation experiments show that this algorithm can solve the unmatched problem and improve the search rate.
