Implementation of P2P file sharing using bi-directional chord protocol algorithm

Abstract

One of the key components of achieving efficiency when looking up on resources is the success of peer-to-peer (P2P) applications. As the structured P2P is an efficient way to locate resources, our study performs two improvements in a structured P2P resource lookup protocol of Chord-based algorithms which is widely accepted. The proposed improvements in detail are presented using two methods. In the first method, the routing information for accurate search of resource is low. In this method, only clockwise direction of resource lookup can be implemented and a unique algorithm is designed for enhancing the finger table in a Chord. A counter-clockwise finger table is also included for generating resource queries in two direction clock wise and anticlockwise increasing the density of neighboring fingers. The proposed model also employs a new functionality of eliminating excess fingers generated by the inclusion of fingers by the suggested model. The results of simulation on effectiveness of the search in the proposed model against the average lookup hops and average lookup delay are presented. The model of algorithm context is extended as finger table resulting in forwarding-storm of routing maintenance messages.
