Abstract

This paper introduces a novel unstructured P2P system able to adapt its overlay network topology to the load conditions. The adaptation is performed by means of a mechanism which is run by the nodes in the network in an autonomous manner using only local information, so no global coordinator is needed. The aim of this adaptation is to build an efficient topology for the resource discovery mechanism performed via random walks. We present the basis of the adaptation mechanism, along with some simulation results obtained under different conditions. These results show that this system is efficient and robust, even in front of directed attacks.
