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.
