Abstract

In this paper, we present a new model for a peer-to-peer system based on Chord, called Hybrid-Chord, to improve the routing performance and data availability of Chord Our main focus is on reducing the number of hops that is needed to locate a data item Through simulations, we demonstrate the improvement of the routing performance and fault tolerance capabilities of the proposed system and compare that with the original Chord system The hybrid system can reduce the number of lookup hops significantly by up to 50% compared to Chord, is robust and handles node failures better than Chord, can always find the desired data with high probability and has better data availability than Chord Above all, the hybrid system has same complexity as Chord.
