The Improvement of Chord Protocol about Structured P2P System
Abstract: Chord protocol is
one of the most classical protocols in structured P2P system, with the good
effect, reliability, high query efficiency, and many other advantages. However,
Chord agreement remains two main shortcomings the one that the searching speed
of resources is slower, and the other that the detention of routing is higher.
This paper in view of these shortcomings, combination with modification, then
put forward the new Chord structure that super nodes and common nodes coexist,
super nodes management general nodes. The new structure using Zipf-law
determines the proportion of super nodes and ordinary nodes. The last, the new
structure is simulated by simulation software, and the improved Chord protocol
make better the previous shortcoming through the new structure compares with
the Chord protocol.
