Dissymmetrical P2P Topology and Resource Locating Algorithm

The paper proposes a dissymmetrical and pure P2P topology based on K-ary-tree architecture named DSKTree topology, with the view of "node symmetrical characteristic", it can solve the unstable and linearly increasing scale problem in existing resource sharing application using pure P2P topology. We also design resource locating algorithm in DSKTree topology. The performance analysis shows that it can optimize the cost of locating and lower the impact to performance of pure P2P topology while the scale of the system increases.
