Advanced Chord Algorithm

Network is a peer to peer (P2P) increasing popularity and now over a day. Systems on top of peer-peer overlay network abstraction of the machine or the physical network topology. Networks for structured and unstructured two types of networks are peer-to-peer name. The network peer to peer unstructured is not applied to cover the network structure. No network unstructured peer provide any organization or network connection optimized algorithms. The structural arrangement of such networks, according to specific rules or algorithms nodes provides specific performance and coverage topology. Therefore, the structure of the peer network coverage link to be set. They are typically distributed hash table (DHT) indexes, such as Chord system. Chord algorithm is relatively simple and successful alternative program to promote the diffusion of structured P2P network, but it must be better to further improve search efficiency. Therefore, this paper aims to improve the Chord structured P2P network discovery process. In order to improve search efficiency, the other to introduce this routing table in the counterclockwise direction, and the original routing table (in the clockwise direction search). Simulation results show that this method improves the work efficiency chord structured P2P network search process to reduce the number of hops.
